Any thoughts on the following? Am I missing something? [I am running R for Windows 0.63.1 on a Win NT 4.0 (workstation, sevice pack #4) box.] Thanks. FC.
...
data(women) names(women)
[1] "height" "weight"
summary(lm(weight ~ height, data = women))
Call:
lm(formula = weight ~ height, data = women)
Residuals:
Min 1Q Median 3Q Max
-1.7333 -1.1333 -0.3833 0.7417 3.1167
Coefficients:
Error: binary operator applied to invalid types
This works on Unix 0.63.1, so no, you're not missing anything. Unless you have something important redefined when you load your workspace. To help debugging in, perhaps you could try something like: hw.sum <- summary(lm(weight ~ height, data = women)) # avoids printing hw.sum # I believe this provokes the error traceback() print.default(hw.sum) debug(print.summary.lm) hw.sum
