...rking on my master thesis, I need to get a plot currents distributed over a surface. I have the data listed in a dataframe with the x coordinates, y coordinates and the value. Im using the persp function but I’ve not found out how to put the data into the z1 variable es <-read.table("RDatalog_pass_dev_1_wafers_1_8V.txt",header=T,sep="\t") x1 <- seq(0,40, length=40) y1 <- x1 z1 <- ? (es[,5]is the column with the data, es[,3] is the x coocdinate, and es[,2] is the y coocrdinate] persp(x1,y1,z1) I will appreciate all help because this will be a nice thing to present in my report....
