tavareshugo / data_carpentry_extras Goto Github PK

Need to fix download of data, which on windows needs to have the method = "wb" option:

download.file("https://github.com/tavareshugo/data_carpentry_extras/blob/master/rnaseq_visualisation/rnaseq_data.RData?raw=true",
              destfile = "data/rnaseq_data.RData",
              method = "wb")

Third part of exercise 3.3 is not showing up code solution

• the tip about modifying the default ggplot theme with theme_set()

from @mvanrongen:

• explain why is the x_int defined as c(1L, 10L) e.g. if as c(1, 10) then R sees it as "numeric"
• adding a picture of a (3D) array would be helpful, e.g. https://towardsdatascience.com/numpy-array-cookbook-generating-and-manipulating-arrays-in-python-2195c3988b09
• in "including checks" it says 'it should not..." which should read 'it should now...'
• in the for loop section you use result <- vector("list", length = N) to create a list. why is this different from before, where you used the list() function to create one? I don't know the answer and it might be helpful to point out the reason to students
• at the note in for loops ('when adding results to...') perhaps add that it's important to check that the empty object should be large enough to contain all the output that is generated in the loop. it's defined here with length = N but that might not be immediately obvious to people who encounter it for the first time
• the link to the separate document with the answer to Exercise 2 does not work
• answer to exercise still has references to "chick" data.
