@Dr_ALI_HS @lukanegoita Hi! We have a blog post about plotting shapefiles and creating nice maps coming soon :)

@lukanegoita Let me know if you can help me make maps in R

Did you know that learning R does not need to involve statistics at all? If math phobia kept you away from R, then check out my online course! It doesn't have to be so hard... coaching.rforecology.com #Rstats #RStudio #datascience #onlinecourse #RforEcology #DataVisualization

@abcmoshs @lukanegoita Great question! It's good to know what people are interested in learning about – we'll try to write a blog post on the topic, so keep your eyes peeled for a tutorial video or post soon. In the meantime, I recommend you check out r-bloggers.com or Stack Overflow for help.

@TheodoreLytras @lukanegoita @alexkara1989 Yeah true, I've definitely been exasperated by having to use merge() or left_join() over and over again. Anyone have any better ideas?

@lukanegoita @alexkara1989 Only drawback that it can't join more than 2, unless you nest multiple merge() calls ...

@GallagherPSean @lukanegoita Yes, I took the course and found it very helpful :)

@SelinaCheng16 @lukanegoita Have you taken the course?

Ever wondered about the difference between long- and wide-format data? We have a new tutorial explaining what they are, some of the pros and cons of each, and how to convert between them! Enjoy!👇👨🏻‍💻 rforecology.com/post/reshaping… #Rstats #RforEcology #DataWrangling #DataScience #blog

@NicoNogueira92 @lukanegoita So glad you enjoyed the post!!

@lukanegoita @SelinaCheng16 Ow, I didn't see the author of that post. Anyways, thanks @SelinaCheng16 ! It works perfectly!!

O Twitter sabe exatamente do que eu preciso! Eu estava quebrando a cabeça para resolver exatamente isso ontem. Já tinha visto a pivit_longer() mas nunca cheguei a usar. Thanks @lukanegoita that's just what I needed!

@GallagherPSean @lukanegoita Yes!! Awesome!

@lukanegoita @SelinaCheng16 This summer I start the R (for ecologists) !

.@brunj7 and I are excited to share the lterdatasampler R pkg! It contains environmental data samples from 8 US Long Term Ecological Research (@uslter) sites - eventually there will be 1 data sample from each of the 28 sites. lter.github.io/lterdatasample… 🧵1/12

@sarah_langsat8 @ocronin_golomb So cool!! Amazing work

Looking for a step by step guide for processing satellite imagery in NASA SeaDAS? @ocronin_golomb and I made an informal guide for processing Landsat-8 and Sentinel-2 imagery (can be adapted for other sensors) github.com/ocean-slang/Se…

@Forensecology @lukanegoita Awesome, thanks for sharing! This is so useful to think about.

In case you've been trying to figure out what to do about all those NAs in your data (and what they even mean!), @SelinaCheng16 just wrote an awesome new blog post on how to deal with missing data: rforecology.com/post/introduct… #RforEcology #rstats #science #ecology #data #datascience

@KGrayson_UR @lukanegoita This looks like it might work -- you could write the instructions and teaching about new functions in a "child document" and just switch it off when grading? stackoverflow.com/questions/4296…

@lukanegoita I've searched and not found any quick options. My Markdown teaching usually includes scaffolded introductions to new functions and a section at the end where students practice. Love to save the scrolling when grading :)

Just released a tutorial on R Markdown where I also explain why I think it's one of the best tools for learning R. Hope this is helpful! youtu.be/K418swtFnik #Rstats #RforEcology #RMarkdown #RStudio #tutorial #datascience #datavisualization #reproducibleresearch #science

@lukanegoita @ESA_org Exciting! Congrats!

It's official! Thank you @ESA_org, my online school RforEcology.com is now an approved content provider for becoming a certified ecologist! Here is more info about their ecologist certification program: esa.org/certification/… #rstats #ecology #ESA #data #RforEcology

@KasimJufar @lukanegoita Yes! What is your specific question?

@KasimJufar @lukanegoita Hi Mohammed, I'm a virtual assistant for R for Ecology – let me know what you need help with!

@daniel_ion @lukanegoita Hi Daniel, I'm a virtual assistant for R for Ecology – thanks for sharing ggpointdensity with us! these figures look awesome. and don't worry, the ggplot2 version will come soon :)

@lukanegoita Great, looking forward to the ggplot2 version. There is also this great extension package 📦 ggpointdensity

Here is my take on how to make quality scatterplots in R: a tutorial for beginners and advanced alike! 👀😁 rforecology.com/post/how-to-ma… #rstats #datavisualization #datascience #rforecology #basics #tutorial #dataviz #academia #data #scatterplot

@numericalguy I'm an assistant for R for Ecology -- good point that y=a+bx linreg is different from forcing a regression through zero. The hope for the video was to discuss the most common and helpful form of linear regression; thanks for addressing one of the exceptions!

@lukanegoita @rstats4ds To all doing linear regression, beware that linear regression to y=bx is not same as y=a+bx.

In case you missed it: How to do simple linear regression with R. youtu.be/iOItuj6q6lg Here is the blog post with scripts and more: rforecology.com/post/how-to-do… #rstats #linearregression #linearmodel #dataanalysis #statistics #datascience #rforecology #tutorial #regression

@lukanegoita Awesome course, thanks Luka!

Calling all #ecologists! Do you feel frustrated with R? My self-paced online course on the Basics of R is designed to make learning R as easy and fun as possible rforecology.com #Rstats #RStudio #datascience #onlinecourse #RforEcology #DataVisualization #ecology #science

Thank you @sarah_langsat8 😩🥺😭

@SeanHardison Hope you recover soon, Sean!!

@sarah_langsat8 @jpschimel We love writing science!!!!!

We also thought we should pose with our copies of #WritingScience by @jpschimel- the book that was so helpful to our scientific writing

@SelinaCheng16 and I defended our undergrad theses today. Long time in the making! Thank you @MaxCastorani and @ScottDoney1 for being great advisors.
