Hi All,
There were lot of diffrences in the R and SPSS results for Exploratory
Factor Analysis.why is it so ?I used standard factor analysis functions
like:--

factanal(m, factors=3, rotation="varimax")
princomp(m, cor = FALSE, scores = TRUE, subset = rep(TRUE,
nrow(as.matrix(m))))
print(summary(princomp(m, cor=TRUE),loadings = TRUE, cutoff = 0.2), digits =
2)
prcomp(m, scale = TRUE)
summary(pc.cr <- princomp(m, cor=TRUE))

I just do coding in R ,but my statistician said teh results vary a lot.I
found quite a number of posts regarding this issue in these links:--
