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

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])
}

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.
