Hi. I am new to R and facing a problem that I cannot solve.
I am writing some basic functions. Then I would like to have a master function
that allows me to call one of the functions which I created, but I cannot
figure out how to do so.
Below is an example. The functions rnormIra and runifIra both seem to work
fine. I do not get an error message when entering the definition of the master
function randomIra; however, it fails when I use it to call another function.
Can someone please help?
Thanks.
Ira
rnormIra = function(n, mean) {
return(rnorm(n,mean,1))
}
rnormIra(10,100) #works fine
runifIra = function(n,min,max) {
return(runif(n,min,max))
}
runifIra(5,20,30) #works fine
randomIra = function(f, ...) {
if(f == rnormIra) {
return(rnormIra(n,mean))
}
else {
return(runifIra(n,min,max))
}
} #no error messages
randomIra(rnormIra, n = 5, mean = 20) #FAILS
randomIra("runifIra", n = 5, min = 10, max = 25) #FAILS
do.call(randomIra,list("rnormIra",5,20)) #FAILS
