## Hello everyone,

## I have an object with 150 elements named "a",

##
## Each element in "a" has 60 values plus a header.

## When I type:
r <- lm(i ~ b)
for(i in a) print(r)
Try instead something like this untested modification:
for(i in seq_along(a)) print(r <- lm(a[i] ~ b) )
## I get 150 times the lm results of the first element of "a"
regressed
with "b",
##
## whereas I would like to have 150 different regression results
from each
element in "a"...
##
## Can someone please help me with the syntax of my loop please?
##
## Many Thanks,
