Re: [R] printing a variable name in a for loop

2006-09-26 Thread David Barron 
This would do it:

 v1 - 5
 v2 - 6
 v3 - 7

 vns - paste(v,1:3,sep=)
 for (i in 1:length(vns)) cat(Hello, vns[i], get(vns[i]), World\n, sep=,)

Hello,v1,5,World
Hello,v2,6,World
Hello,v3,7,World

 Hello,

 How do you print a variable name in a for loop?

 I'm trying to construct a csv file that looks like this:


 Hello, variable1, value_of_variable1, World,
 Hello, variable2, value_of_variable2, World,
 Hello, variable3, value_of_variable3, World,


 Using this:

 for (variable in list(variable1, variable2, variable3)){

 cat(Hello,, ???variable???, variable, , World,)
 }

 This works fine if I'm trying to print the VALUE of variable, but I want to
 print the NAME of variable as well.

 Thanks,
 Suzi

This is a teetering heap of assumptions, but is this what you wanted?

  cat(Hello,deparse(substitute(x)),x,World\n,sep=, )

Example:

lst - list(variable1, variable2, variable3)
for (kk in seq(along=lst)) {
  name - names(lst)[kk];
  value - lst[[kk]];
  cat(Hello,, name, value, , World,)
}
