Hi I have a vector of data lets call zz (40 values from 4 samples) the data is already in groups, i can even split up the samples using SampA <- zz[,2:11] SampB <- zz[,12:21] SampC <- zz[,22:31] SampV <- zz[,32:41] I would like an output that gives me 4 boxplots on one plot one boxplot for the set of 10 values how can i do this in R
