R help - Jan 2014 - Assigning a successive set of values to newly created variables

Hi,
May be this helps:

?set.seed(24)
?x<-rnorm(10)


vec1 <- seq(0.5,2,by=0.5)
for(i in 1:4){
?assign(paste("x",i,sep=""),x+vec1[i])
?}
A.K.


Hi all, I have been trying to figure this one out but I'm at a dead end. I
want to write a loop that automatically create a series of values
based on a previous variable. For example, I can initialize the first 
set of values for a variable "x" as 10 scores from a normal 
distribution. Then, I can create 4 new variables labeled x1, x2, x3, x4 
etc. Now, I want x1 to be the original x + a constant (say .5), x2 to be x1+.5,
x3 to be x2+.5 etc.

What I have so far accomplishes the first step (x1 as x+.5) but I
 can't figure out how to index the rest. Any help would be greatly 
appreciated! 

x<-rnorm(10) 
for(i in 1:4){ 
? ? ? ? assign(paste("x",i,sep=""),x+.5) 
? ? ? ? } 

p.s. I am trying to do this as a component of a function that 
will be generalized based on user input so the example above is a 
simplified version.

Also:
xNew <- x
for(i in 1:4){
?xNew <- xNew+0.5
?assign(paste("y",i,sep=""),xNew)
?}
identical(x2,y2)
#[1] TRUE
?identical(x3,y3)
#[1] TRUE
A.K.
