Spider diagrams

Lines are drawn from each atomic number for each sample. Right now, my data frame looks like: SAMPLE SITE V3 LA.NASC LAATNUM CE.NASC CEATMNUM 1 1A:001

The function (1) prints a lot of output without any

Now, I can do this manually by changing the values of X and save each resulting array/vector in
