Can't understand error message :-{
...rying to plot
the residuals from a linear model against another variable in the data frame.
Here are the lines I'm trying to execute:
size <- read.table(file="/u67/abasl70/surveys/annenberg/mega/smschl.dat",

sizef <- data.frame(size, row.names=size$unit)
attach(sizef)
mschmod <- lm (mavgres ~ crimesch + socstat + povnojob + ploinc94 + aa94 +
hisp94 + minty94 + mixed94, data=sizef)

How to set axis labels?
...bother everyone with such a basic question again, but I can't seem to
set my axis labels. When I use
title(ylab="String")
"String" just overwrites the variable name, producing a mess. When I try to put
ylab="String" in the plot function, like this:
plot(residuals(mschmod) ~ size94, ylab = "Productivity Adjusted for Context")
I get this message:
Error: formal argument "ylab" matched by multiple actual arguments
Thanks for the help (again).
