Dear all, 

i have a programming problem that should be simple, though i am stuck with it. Please note that this is not a specific geonames problem, though i use it as an example - it´s just a basic problem with lapply.

I use the geonames webservices with the R geonames packages which works almost smoothly. 
I have a vector of Zipcodes and i want to do a geonames lookup for all of them, which should not be a problem. 
Of course i could create a loop for that one, but i think lapply should be possible, too. 

The problem is to hand over the variable to the lookup function. 

lapply(zipcodes,GNpostalCodeLookup(postalcode=zipcodes,country="US"))

where zipcodes is my vector of zip codes an GNpostalCodeLookup is the function that gives back some information like longitude and aptitude etc. Is it possible to use lapply in that context or can I just use it in contexts like lapply(somelistofvectors, mean) ?

all i´d like to have is some data.frame like this

zip     apt    long
1234  xy.x	  xx.x
1235  ax.x   aa.a

thx in advance

matt
