I think this wants a statistical discussion, which is OT here.
stats.stackexchange.com would be a better place to post for that.
However, if I understand correctly, using pls or anything else to try
to fit (some combination of) 501 variables to 16 data points -- and
then crossvalidate with 6 data
Hi,
I'm trying to fit PLSR model in R with 'pls' package with 22 samples (16
train, 6 test). I know that basic for considering of number of component is
cross-validation (in my case 'LOO') and then I should choose number of
component with minimum of RMSEP (or first minimum). But problem i
Hello Catalin, you could have a look on this link first for ideas in
constructing your own script.

Dear all!
Please help me with a script or package to compute a Gaussian filter. I
have a time series (like average mean temperature from 1901-2014) and I
want to extract low, high and band pass frequencies using a Gaussian filter
with 32 years window.
Thank you very much!
Best regards!

Yes, I was replying to the OP's query **as stated.** I try to avoid
guessing what the OP really *meant*, although I grant that sometimes
this may be necessary.
But do note that the leading 0's in seq() *are* unnecessary:

[1] "01" "02" "03"

Bert, your solution seems to presuppose that the programmer
knows beforehand that the leading digit in the number is "0"
(which in fact is clearly the case in Nabila Arbi's original
query). However, the sequence might arise from some process
outside of the progammer's contgrol, and may then either
No need for sprintf(). Simply:
> paste0("DQ0",seq.int(60054,60060))
[1] "DQ060054" "DQ060055" "DQ060056" "DQ060057" "DQ060058" "DQ060059"
[7] "DQ060060"

Dear useRs:
I am having difficulty understanding how to make a legend in ggplot when I only
want certain geoms to be indicated, in the presence of nested groups. An
example:
require(tidyverse)
dat <- tibble(X=rep(seq(4),3),
# fake data
Y=c(-1.11, -0.46, 0.02,
