Dear Ms. Gobin,
There would appear to be a typo in the package manual that appears on
CRAN. Doing ?Frechet (it would be nice to have this aliased also to
"frechet") points you immediately to frechet. With "frechet2"
substituted for "frechet" your code, everything works.
cheers,
Rolf Turner

Dear Mr Michael,
Thanks a lot for your guidance. The pdf file describing VGAM package has
mentioned 'frechet' in the example, so I got the error.
Regards
Katherine

Dear R forum,
I am trying to execute following code (Page no 259 - VGAM.pdf)
#
.........................................................................................................................
library(VGAM)
set.seed(123)
fdata <- data.frame(y1 = rfrechet(nn <- 1000, shape = 2 + exp(1)))
with(fdata, hist(y1))
fit2 <- vglm(y1 ~ 1, frechet, data = fdata, trace = TRUE)
#
.........................................................................................................................
Is it not called frechet2?
However, I receive following error
Error in vglm(y1 ~ 1, frechet, data = fdata, trace = TRUE) :
object 'frechet' not found
Earlier there used to be a function called "frechet3" which I guess has been
withdrawn by VGAM.
Kindly guide
Katherine
