Hi guys, Very new to R and your help would be highly appreciated for the following problem. I am trying to create a simple function which registers values within an array through a for loop. These are the steps I have followed:
1) Declared 2 global matrices 2) Create function mat() with i as an input 3) constructed the for loop 4) called mat(2) The problem is that when i try to get y[4] and f[5] the output is: [1] NA my concern is that i am not addressing any of the following topics: 1) definition of global variable 2) the argument does not go through the for loop 3) the matrices definition is not correct 4) the function do not return any values 4) other.. My code is listed below: y=c(NA) f=c(NA) mat<-function(i) { for (k in i:10) { y[k]=k+1 f[k]=y[k-1]/2 } } mat(2) Any thoughts or recommendations would be highly appreciated. Thanks in advance, N -- View this message in context: http://r.789695.n4.nabble.com/Simple-Function-tp3035585p3035585.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
