If you want to see internal structure do str(x) or str(y) > save(y,file="ydata") > Am I computing the mean correctly and how to I show the value of the mean to the screen? Maybe its time to have a small glimpse into some basic documentation like R-intro. I may guess you want mean of columns 25:46. If this is true, then colMeans(dat[, 23:46]) prints means for defined columns. And boxplot(dat[, 23:46]) gives you boxplots for each column. But enough of speculation what do you really want.
