Hi I have the following df and I created two subsets but I don't know how to use these subsets as the colors of my plot.
data.frame': 36919 obs. of 162 variables $TE :int 38,41,11,52,48,75,..... $TR :int 100,210,548,546,..... $Command :factor W/2229 levels "_localize_PD","_localize_tre_t2","_abdomen_t1_seq","knee_pd_t1_localize"... and the subsets are names in Command which has t1 or t2 letters: hast1=grepl("t1", df$Command, fixed=TRUE) hast2=grepl("t2", df$Command, fixed=TRUE) the colors I want in my plot are : hast1 and hast2 Thanks for any help.
