@JARS3N @rstatstweet If they all have the same structure, would make sense to load the whole dataset via arrow and then partition them (hopefully also to less files).

have a directory of 1200 csvs I converted to feather assuming that the overall file size would be smaller but the difference is 3.6G & 4.52G. Not the result I was hoping for. #R #Rstats #feather

Big THANK YOU to @drillybit for creating the {gtsummary} cheat sheet! It's now available on the RStudio page 🕺🪩🕺 rstudio.com/resources/chea… #rstats #DataScience

@simonw #rsrats #arrow

If someone gives you a CSV file with 100,000 rows in it, what tools do you use to start exploring and understanding that data?

@hadleywickham Why not: squish <- \(x, min, max){ pmin(pmax(x, min), max) }

e.g. rescale_z <- function(x) { (x - mean(x, na.rm = TRUE)) / sd(x, na.rm = TRUE) } squish <- function(x, min, max) { case_when( x < min ~ min, x > max ~ max, TRUE ~ x ) }

What tweetable #rstats function have you written recently to reduce duplication in your data analysis code? I'm looking for some inspiration as I re-write the functions chapter in R4DS.

@hadleywickham I use this for consistently plotting with wanted defaults

@PR0GRAMMERHUM0R #rstats a == 0

@newdata_learner @rstatstweet 1. The rowwise() identifier is unnecessary here unless you use summarise(). 2. starts_with() and the underline are safer to use. i.e., if you had a variable called width_height_ratio, it would not be selected. 3. Remember to ungroup.

@newdata_learner @rstatstweet See: dplyr.tidyverse.org/articles/rowwi…

Hey #rstats folks, could you help out a beginner with this error? I am trying to combine select with a rowwise operation You can see the reprex right here: community.rstudio.com/t/error-in-mea…

@FelicienLL @rstatstweet Palmer penguins allisonhorst.github.io/palmerpenguins/

Hi #rstats folks, I have "introduction to R" courses to prepare, and I'm looking for datasets easy to play with in order to learn data wrangling, visualization etc... What do you use apart from mtcars, iris etc...? Do you have any favorites? Thank you!

@CristalyneBell Lubridate makes it smoother lubridate.tidyverse.org

Is it just me or when you are learning to code, nothing has the power to wreck your day like dealing with date formats? #SAS #RStats #RLadies

During development, I am used to rearranging my #rstats #tidyverse pipe chains a lot so I terminate the chain with "{.}" This breaks with the native pipe. What to use instead? Or just stay with "%>%" and reveal myself to be old, like using two spaces at end of sentence? Thanks.

@FraserSneden What you are looking for is to align the position_dodge

Anyone want to tell me why my (very simple) plot isn't aligning correctly? I don't understand as I've more or less just copied code from elsewhere. The bottom is cut off in the screenshot, but it only has 2 ticks (as it should) #RStats

@seriouswildlife @rstatstweet Why not bind_rows() them?

@LandaIsidro @rstatstweet ^ raw.githubusercontent.com/rstudio/cheats…

@AvishaiTsur @rstatstweet Oo thanks for the tips! Gonna incorporate that. Is there an equivalent to the dollar signs for prefixes? Or do you simply place it in front to indicate that?

2 lines of code to replace 52!! To partially rename multiple variables. Always brings me joy to find more efficient ways of doing things. The simple things. #rstats #purrr #tidyverse

@alejandrohagan @LandaIsidro rename_all() is possible but has been superseded by rename_with().

@LandaIsidro i think dplyr::rename_all() will do the same thing as well

@geokaramanis You may already know this by now--it also works with plotting

TIL that if you do a variable assignment inside parentheses, R prints the variable! #RStats

@at_schill_j If you enjoyed all(), maybe you would also appreciate any().

Today in #rstats I learned: the all() function checks a vector and passes true if all items within it are true... I'm a bit ashamed I didn't know that sooner 🥲 RIP to all of the {sum(boolean_vector) == length(boolean_vector)} lines I've written.

@drrachelbrenner If you have specific questions, I highly recommend @R4DScommunity. It is not a guide, but a community

Hey #rstats community, I'm looking for a guide on importing and cleaning data for use in #tidyverse. More granular/detailed than R for Data Science. Any Recommendations? Hands-On Programming with R?

@Kate_J_Fuller @_mikoontz The only reason I know this is because I did the same, and someone enlightened me. So now it is your turn to pass it on :)

@AvishaiTsur @_mikoontz Whaaat! I’ve been such a fool!!

Give me your under-rated and under-used R function favourites. I'll go first. attributes() #RStats #rspatial
