R help - Apr 2009 - For Loop Syntax

Hi there,

 

Just wondering if someone can help me with the correct syntax to use
with for loops?

 

I have split my original file by count, & wish to first of all assign
new tables based on the splits.  Then I just want to create a new
variable.  Please see code below.

 

This code works outside of a loop so I am just trying to code so I don't
have to repeat numerous times.

 

Many thanks in advance,

Bronagh

 

A2 = split(A1,A1$count) 

 

for(i in 1:10){

trial[i]       <- data.frame(A2$`i`)

trial[i]$BLD[i]   <- triali$BLD

trial[i]$count <- triali$BLD <- NULL

}

What do you expect this statement to do:

trial[i]       <- data.frame(A2$`i`)

what is `i` supposed to mean?  What is it that you want to do?
