It's very seldom that I disagree with
Bert, but here is one time.
I don't think "An Introduction to R" is
a suitable first read for people with
little computational experience.
Better (I modestly suggest) would be:
http://www.burns-stat.com/pages/Tutor/hints_R_begin.html
which includes some other references.
'Hints' is imperfect and incomplete but
it suffers slightly less from the curse of
knowledge than a lot of other R documentation.

... and you can of course do the assignment:
Bndy<- paste (BndY,"to",50+seq_len(BndY), "mN", sep = " ")
"An Introduction to R" tells you about such fundamentals and should be
a first read for anyone learning R.

Don't do this! paste() is vectorized.
paste (BndY,"to",50+seq_len(BndY), "mN", sep = " ")

Dear R helpers
I'm trying to make up some labels for plot from this vector
BndY<-seq(from = 18900,to= 19700, by = 50)
using
Ylab<-for(i in BndY) {c((paste(i," to ",i+50,"mN")))}
but the vector created is NULL
However if i use
for(i in BndY) {print(c(paste(i," to ",i+50,"mN")))}
I can see the for loop is making the labels I'm looking for but not sure
on my error in assigning them to a vector
Thanks in advance
