Still overkill, I believe.
" Unlike using the numeric levels, that doesn't fail if some of the
levels I expect are absent; it only fails (and does so visibly) when
there's a value in there that I haven't assigned a coding to. So it's
a tad more robust. "

Dear R experts,
Maybe my question is too basic and I apologize for that. I am having an
issue currently by trying to change manually the symbols of the series. I
need to put them manually, instead of using the symbols that R gives by
default and produce a plot with the classic style. For example I

Depends whether you want to recode all or some, and how robust you want the
answer to be.
recode() allows you to recode a few levels of many, without dependence on level
ordering; that's kind of neat.
tbh, though, I don't use recode() a lot; I generall
Granted,, there are better solutions than my "KISS" (keep it simple and
stupid) example.
Hopefully, Christoph will have learned from both.

Hi Margaret,
This may be a misunderstanding of your request, but what about:
mydata<-data.frame(oldvar=paste("topic",sample(1:9,20,TRUE),sep=""))
mydata$newvar<-sapply(mydata$oldvar,gsub,"topic.","parenttopic")

Dear Margaret,
You've had one suggestion of an alternative for recoding variables, but in

Well, I think that's kind of overkill.
Assuming "oldvar" is a factor in the data frame mydata, then the
following shows how to do it:

> d <- data.frame(a = sample(c(letters[1:3],NA),15,replace = TRUE))

a
1
2 a
3
4 b
5 a
6 b
7 a
8 a
9 a
10
Your code suggests that you do not understand R or what you are doing. The line
mydata$newvar[oldvar = "topic1"] <- "parenttopic"
does not recode cases where oldvar is "topic1", it creates a new variable
called oldvar (not the same as mydata$oldvar) and sets it to "topic1" because a

Dear Petr,
I attached a sample file, which contains the first 4 products.
It is more that I have: 157 weeks, 19 different Stores and 22 products:
157*19*22 = 65,626 rows. And as I sated I have roughly 63,127 rows. (so some
have to be missing).
All the best,
