Hey, all!
I've got a report that uses datatable from DT to create an rmarkdown html that
looks great as an html but when I try to print it, to a printer, or to a pdf
the colors I've assigned to cells are not displaying. I'm using chrome and I've
clicked on the Background graphics button there,

Yes, I was confused: In is.na(x) <-value, value is supposed to be an index
vector, clearly stated on the help page. So Bert�s suggestion is the way to go.
Thanks to all, G�ran

I think that
is.na(x) <- i
generally does the same to x as does
x[i] <- NA
I say 'generally' because some classes (e.g., numeric_version) do not allow
x[i]<-NA but do allow is.na(x)<-i. It is possible that some classes mess
up this equivalence, but I think that would be considered a bug.

To do what the OP wanted, one can use:
x <- c('A', 'B')
is.na(x) <- x=='A' ## rhs is a logical index vector
## yielding
> x
[1] NA "B"
Cheers,
Bert

... and note that my previous version can be simplified using R's pipe
syntax to:
do.call('rbind',Total[select.stat]) |>
subset(sensor == 'thermometer', code)
## which calls the subset.data.frame() method that gives:
code
Station1.1 2583
Station4.4 4453
Station5.3 3179

I don't find _either_ of these acceptable.
On the other hand,
x[ is.na( x ) ] <- 1
should have no effect on x.

maybe this will make it clear
x <- c(a=1, b=5)
is.na(x) <- "b"
i.e. your second case is dealing with a named vector

OK, but

"A" "B" NA
What happens?

Following Bert Gunter's suggestion, I wonder why the data are in separate
frames (with hard-coded values) in the first place. You could put them in a
text file and call read.table. If you provide a header and put a meaningful
station name at the start of each data row then rownames of your data

Thank you Simon,
It seems not to be related to the R package but rather to the OS,
(just got the same error when installing the shiny R package from
CRAN).
I am on an M1 mac running Windows ARM in Parallels. Installed a
x86_64-w64 R version.
