Hi R-Helpers:
Im trying to fit the same linear model to a bunch of variables in a data
frame, so I was trying to adapt the codes John Fox, Spencer Graves and Peter
Dalgaard proposed and discused yesterday on this e-mail list:
for (y in df[, 3:5]) {
mod = lm(y ~ Trt*Dose, data = x, contrasts = list(Trt =
contr.sum, Dose = contr.sum))
Anova(mod, type = "III")
} ## by John Fox
or
for (myname in names(myframe)){
mycall <- substitute(lm(myvar~etc.etc.....),list(myvar=as.name(myname)))
myfit <- eval(mycall)
print(summary(myfit))
} ## by Peter Dalgaard
But instead of printing summary or Anova results, I need to generate a list
containing all the lm() objects.
Is that possible? How?
Thanks, Gabriela.
