vector w/o arithmetic addition for boxplot
...ectors for a box
plot of the residuals of a linear regression. It is performing arithmetic
addition on the 16 individual variables that I want individual box plots
for.
I have 16 race*treatment variables that were created from cleaned
data.frames for race and treatment independently: t1W, t1B.....t4W, t4B,

class(t1W) produces "numeric" (1000 observations of 1's and 0's)
To create the box plot I am using
boxplot(residuals(IRR)~ treatRace_clean)
where I have tried treatRace_clean as both of the following
treatRace_clean <- as.factor(as.vector(t1W + t1B + t1H + t1...
