Simple conditional plot

[rstudent]

I just started using R last week.

I have a dataset with 3 columns - Plate, Well and Raw

I need to make a simple plot(Well~Raw) but only when Plate = 101

Thanks for your help.

Try

plot(Well~Raw, subset= Plate==101)

?subset

# Some plotting paradigms allow you to use a subset = <argument> but  
any  program that had a data= option would allow data=subset(dfrm,  
Plate==101)

newseRs:  Remember to use double "=="'s

Another possibility without using subset():

plot(Well[][Plate==101]~Raw[][Plate==101])

This also works to '>=' '<=' and other conditions.
