I ran this code in R Studio
Output<- data.frame(participant_df, GroupSize_df, PSE_df, slope_df)
Output_sorted <- Output[arrange(Output, desc(participant_df))]
And I got this error:
Error: Error in `arrange()`: ℹ In argument: `..1 = participant_df`.
Caused by error: ! `..1` must be size 172 or 1, not 86.
How to fix this error?
I want to put my Output data frame in alphabetical order according to the strings in the participant variable
