R help - Oct 2009 - changing a matrix from class data.frame to class dist

Dear,

I have a data frame object (FSTc) which is in fact a matrix of class 
data.frame but created from a txt file using the command
FSTc<-read.table("FSTcmatrix.txt", header=T)

I would like to transform it in a distance matrix of class dist to use 
it with the ade4 package.

I'm quite sure this is a simple operation but i just don't have the 
commands.

Could anyone help?

Thank you

Maxime

Not sure that is possible (in R terminology anyway.). Dataframes are  
lists.

?dist

#which points to

?as.dist      # which is a coercion function
