Can't understand error message :-{
...are the lines I'm trying to execute:
size <- read.table(file="/u67/abasl70/surveys/annenberg/mega/smschl.dat",
header=T)
sizef <- data.frame(size, row.names=size$unit)
attach(sizef)
mschmod <- lm (mavgres ~ crimesch + socstat + povnojob + ploinc94 + aa94 +
hisp94 + minty94 + mixed94, data=sizef)
plot(mschmod$residuals ~ size94)
The last line gives this error message:
Error in model.frame(formula, rownames, variables, varnames, extras,
extranames, : variable lengths differ
In fact, the lengths are different:
> length(mschmod$residuals)
[1] 379
> length(size94)
[1] 384...
