Hi
Im working 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 Ive 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.
