Dear kd, thanks for your fast reply :-D hm, I thougth, F is normally the abbrevation, but in R FALSE represents "false"? Anyway, your function works. I had actually a little more complicate functions (put I posted in the forum first an easier example): f<-function(a,b)((1/(sum(sqrt(1:a*sqrt(b)

[R] Problem with apply list to function: numerical expression has 4 elements: only the first used

Hello , I want to try R for statistics. Therefore, I defined a function f with parameters m and k, which calculates a to sqrt(x) proportional density function: f <- function(m,k)((1/(sum(sqrt(1:m*sqrt(k)) A function F sums the results in order to get a distribution function: F <- function(

Re: [R] Problem with "apply"

Hi Alan, You can avoid the if() else() you're using in your function by replacing it with the recode() function in the car package. I'm pretty sure it will speed up your function. See ?recode after loading the car package: require(car) ?recode HTH, Jorge On Wed, Apr 22, 2009 at 2:56 PM, Alan

I'm not sure, but I think that using the "cut" function would solve your problem? ?cut On Wed, 22 Apr 2009 14:56:10 -0400, "Alan Cohen" wrote: > Hi R users, > > I am trying to assign ages to age classes for a large data set (123,000 > records), and using a for-loop was too slow, so I wrote a fu

[R] Problem with "apply"

Hi R users, I am trying to assign ages to age classes for a large data set (123,000 records), and using a for-loop was too slow, so I wrote a function and used apply. However, the function does not properly assign the first two classes (the rest are fine). It appears that when age is one digi
