Hi:
I do not know why the function decostand is not found in my vegan library, I have downloaded the package recently, and it seems to work well..Do you have any suggestion?

as.POSIXct month problem
Hi everybody
When I try example of strptime
x <- c("1jan1960", "2jan1960", "31mar1960", "30jul1960")
z <- strptime(x, "%d%b%Y")
The result is;
> z
[1] NA NA NA NA
I have got the same result with complete form of month but not with numeric
form.
Any idea?

Error in family$family : $ operator is invalid for atomic vectors
Dear List,
I'm having problem with an exercise from The R book (M.J. Crawley) on page
567.
Here is the entire code upto the point where I get an error.
data(UCBAdmissions)
x <- aperm(UCBAdmissions, c(2, 1, 3))
names(dimnames(x)) <- c("Sex", "Admit?", "Department")
ftable(x)
fourfoldplot(x, margin = 2)
dept<-gl(6,4)
sex<-gl(2,1,24)
