[R] Plot

[Tyler Rinker]

I noticed I was remiss in addressing your origin question:
Use the xlim and ylim, setting the lower limit to 0.  Here's an example of this with the CO2 dataset:


plot(uptake~Plant, data=CO2)


plot(uptake~as.numeric(Plant), data=CO2)


plot(uptake~as.numeric(Plant), data=CO2, ylim=c(0, 50), xlim=c(0, 14))



Cheers,Tyler

When I enter the following code I instead get 3 separate boxplots for each of the three different protein concentrations ...
