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
