That is likely?because?ferm is a factor. ?A scatterplot is two numeric
variables. ?To make it a scatterplot wrap ferm with as.numeric.?

Subject: [R] Plot
Hello,
I am trying to make a plot of the rates of an enzyme against three different
protein concentrations (there are 45 rates in total and split up into 3 groups
of 15, each receiving one of the 3 protein concentrations). When I enter the
following code I instead get 3 separate boxplots for each of the three different
protein concentrations ...
plot(rate ~ ferm, data=LDH, col=LDH$rate,
pch=c(17,18,19)[(as.numeric(LDH$rate)%%3)+1])
but I want a scatterplot showing 3 different lines indicating each of the
protein concentrations. I'm not sure if I need to tweak my data set in order
to get what I want?
I was also wondering how to include the origin (0,0) in the plots. I'm not
sure if I'm missing something on the plot help page?
Any help would be appreciated. Thanks so much.
