[R] Looping through names of both dataframes and column-names

Hello all, This seems like a pretty standard question - suppose I want to loop through a set of similar data-frames, with similar variables, and create new variables within them: nl<-seq(1,5)for (i in nl) { assign(paste0("df_",nl[i]),data.frame(x=seq(1:10),y=rnorm(10)))} ls()[grep("df_",ls())]

[R] Undesired vertical lines in png file output using 'cairo-png'

he error - it's something specific to 'cairo-png'. The vertical lines appear to be empty, i.e. transparent. Any guidance or assistance would be greatly appreciated. Regards, Daniel Egan -- [image: Betterment]*Daniel Egan |* Director of Behavioral Finance and Investing at Better
