I have created a scatter plot that has come out okay but I am having trouble
with the x axis. My data consists of 4 treatments but these treatments are
days so R keeps reading them as numeric and making my x axis continuous.
Here is what I have so far:
plot(pair$MC~pair$Day, pch=c(19,24)[as.factor(Cookie)],
main='Paired t Test',
xlab='Days in Field',
ylab='Moisture Content (Percent)')
I have also done: as.factor(Day) to change it to 4 levels and when I do
is.factor(Day) it returns with FALSE.
I'm assuming this is the reason that I get the message that my x and y
lengths differ when trying to convert my x axis using:
axis(side=1, at=c(0,15,30,45)
When I switch my numbers to words (i.e. zero, fifteen...) it only brings up
a boxplot and I specifically want the points so I can assign different pch
by group. Am I totally missing something here?
