Hi,
I am unable to do something fairly simple. I have matrices called
Table1,..., Table10. I want to be able to print them using a loop. So
I wrote:
##################
for (i in 1:10){
disp<-paste("Table", i, sep="")
eval(parse(text=disp))
}
##################
but this produces no output. Any ideas?
Dear tzygmund,
Here are two suggestions:
# Suggestion 1
for (i in 1:10){
disp<-paste("Table", i, sep="")
print(get(disp))
}
# Suggestion 2
disp <- paste("Table", 1:10, sep="")
sapply(disp, function(x) print( get(x) ) )
See ?print and ?get for more information.
HTH,
Jorge

Jorge, Your suggestions produce the names of the matrices and not the contents. Sorry if this was not clear in the question.

Ah, apologies. In the backing and forthing, I assigned the names to the matrices. All sorted. Thanks!
