Hi Maria, Perhaps something like this: mldf<-read.table(text="Sample Cu Zn Mn M1 1 5 10 M2 2.5 11 8 M3 1.15 11 12 M4 2 4 30 M5 8 15 35", header=TRUE) matplot(mldf,type="b",pch=c("C","Z","M")) Jim On Mon, Dec 5, 2016 at 11:25 PM, Maria Lathouri via R-help wrote: > Dear al

Re: [R] scatter plot of numerical variables against different sample ids

Hi Maria, What happens is that R plots with boxplots (explaining the horizontal lines, i.e. boxes with n=1) when the x-variable is a factor. What you can do is transform your Sample column into numeric and then plot it, with some adjustment of axis labels. For example: datf <- data.frame(Samp

[R] scatter plot of numerical variables against different sample ids

Dear all I know that my question is very simple but although I tried to find an answer online, I couldn't and I am stuck.  I have a dataset of three numerical variables measured in different samples ID. Something like this: Sample        Cu        Zn        MnM1               1          5
