Hi:

CW.lm <- lm(weight ~ Diet, ChickWeight)
resid.CW.lm <- resid(CW.lm)
as.data.frame(resid(CW.lm))[1:10, ]      # (nope)
 [1] -60.645455 -51.645455 -43.645455 -38.645455 -26.645455  -9.645455
 [7]   3.354545  22.354545  46.354545  68.354545
# convert residuals to one column matrix, then convert to data frame:
as.data.frame(matrix(resid(CW.lm), ncol = 1))
              V1
1    -60.6454545
2    -51.6454545
3    -43.6454545
4    -38.6454545
5    -26.6454545
...

HTH,
Dennis
