Dear all,
I would like to know how could I execute a sequence or orders with just a
function, i.e, that just typing the function name, R gives me all the parameters
I want (for instance, if I want to see the summary, the standard deviation, the
number of valid cases, etc of a dataframe just with one function). I have tried
with the following, but just compute the second argument of the body, i.e., the
summary:
resumen<-function(x) {
apply(x,2,sd,na.rm=TRUE)
summary(x)
}
Thank you very much for your help!!

Something like: resumen<-function(x) { print(apply(x,2,sd,na.rm=TRUE)) print(summary(x)) } Or resumen<-function(x) { return(list(apply(x,2,sd,na.rm=TRUE), summary(x))) } Hope this is helpful, Dan Daniel Nordlund Bothell, WA USA
You don't see the standard deviations because
only the final result (the output of summary() in
your case) is output by the function, not the
intermediate results (the results of the apply()
function in your case).
Try this:
resumen<-function(x) {
print( apply(x,2,sd,na.rm=TRUE))
summary(x)
}

Three, all named "describe", can be found in the Hmisc, psych and prettyR packages. Jim

Now you calculate it and it is discarded. To save it, try something like: resumen<-function(x) { y = apply(x,2,sd,na.rm=TRUE) summary(y) } Or print statements on both lines, as the others suggested. cheers, Paul -- Drs.
