Subject: 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 ? ? ? ? ?10M2 ? ? ? ? ? ? ? 2.5 ? ? ? 11 ? ? ? ? ?8M3 ? ? ? ? ? ? ?1.15 ? ? ?11 ? ? ? ? 12 ?M4 ? ? ? ? ? ? ? ?2 ? ? ? ? 4 ? ? ? ? ?30M5 ? ? ? ? ? ? ? ?8 ? ? ? ?15 ? ? ? ? 35
I would like to plot these variables (Cu, Zn, Mn) (in y-axis) against the Sample ID (in x-axis) in a scatter plot with lines as I want to see how they change in the samples.
I tried using the command>plot(Sample, Cu, type="l", lty=1, col="red")
but I wouldn't get a line. Actually, I would get some small horizontal lines in each point. I tried to use type="p" but I would get the same thing.?
I would very much appreciate if you could help me on that. Apparently, I am missing something.?
Thank you in advance.?
Kind regards,Maria
