HI, all, How can i check the variables that is currently being loaded.. ls() only list the variable name, but not the summary of the variable, like the dimension of the variable etc.. Is there a command in R, which is equivalent to "whos" in matlab, which let me check the variables currently loaded in Matlab.. also, Does anyone have recommendation on ~a good reference to R.. I could not find the answer to my Q in the documentation included with R package.. thanks, yan
You may want to just try summary(varname) or more likely you want str(varname). -roger _______________________________ UCLA Department of Statistics rpeng at stat.ucla.edu http://www.stat.ucla.edu/~rpeng On Wed, 15 Jan 2003, Yan Yu wrote:> HI, all, > How can i check the variables that is currently being loaded.. > ls() only list the variable name, but not the summary of the variable, > like the dimension of the variable etc..

Hallo
you can try this function

# Posted by Dan Putler At 2002-07-15 16:13
# As part of the obveRsive GUI project, we've written a function with much
of
# the functionality that Patrick Connolly was suggesting (which is a bit more
# compact than the output from ls.str()). Alas, no date capabilities. The
# function is call ls.objects(), and example output appears below:
# modified by me 20.7.2002
ls.objects <- function (pos = 1, pattern, mode = NULL, type = NULL)
{
Obj.Name <- ls(pos = pos, envir = as.environment(pos), pattern =
pattern)
nnn.m<-sapply(sapply(Obj.Name,get),mode)
nnn.c<-sapply(sapply(Obj.Name,get),class)
nnn.d<-sapply(sapply(Obj.Name,get),dim)
Obj.length<-length(nnn.m)
nnn.pok<-rep(0,Obj.length*2)
dim(nnn.pok)<-c(Obj.length,2)
for (i in 1:Obj.length) nnn.pok[i,1]<-as.numeric(unlist(nnn.d[i]))[1]
for (i in 1:Obj.length) nnn.pok[i,2]<-as.numeric(unlist(nnn.d[i]))[2]
nnn.d<-nnn.pok
vyber<-is.na(nnn.d)[,1]
nnn.d[vyber,1]<-sapply(sapply(Obj.Name,get),length)[vyber]
