Re: [R] string question
You can try noquote also:
noquote(paste('abc', '"xyz"', sep = ""))

Re: [R] string question
cat() is probably what you want, but note that print()
has a 'quote=' argument that you could set to FALSE:
print(qr2, quote = FALSE)
See ?print.default

When you print a string, it escapes the quotes with a backslash. That's
a property of the print() function,
not the string itself.
If you want to see the string, use cat(). The nchar()
function is also useful:
str1 <- '"xyz"'
qr2 <- paste('abc',str1,sep='')
print(qr2)
[1] "abc\"xyz\""
cat(qr2,'\n')
abc"xyz"
nchar(qr2)

Re: [R] String question

Will this do?
temp <- paste("m", 1:3, sep="",collapse=",")
Unfortunately not, because I explained the example not detailed enough.
The string could have different Items, like November, December, Monday,
Tuesday, Daylight and so on
Therefore I must count the Items of the string separated by "," or
change the vector to a string
The right hint was there, I think:
> paste(c("m1","m2","m3"),collapse=",")
[1] "m1,m2,m3"

Just thought I'd show you a solution from the other direction, in
addition to those that all other have posted:
temp <- paste("m1","m2","m3",sep=",")##Generate string
nchar(gsub("([^,])","",temp))+1## Count commas in the string and add 1.

Isn't it same like

[1] "November,December,Monday,Tuesday"
I also thought you actually wanted

[1] "November.1,December.2,Monday.3,Tuesday.4"

Re: [R] String question
Hi Baptiste,
Isn't paste doing exactly this?
yes indeed - surprising
temp <- c("November", "December","Monday","Tuesday")
paste(temp, collapse=",")
paste(temp, sep=",") I tried to use sep :-(
Arguments
|...| one or more *R* objects, to be converted to character vectors.
|sep| a character string to separate the terms. Not |NA_character_
|.
|collapse| an optional character string to separate the results. Not
|NA_character_ |.
and I did not realize that I separated the wrong part ...
Kind regards Knut

Yes, spot-on! I got involved in the confusion resulting from
the use of "sep" in previous postings.
I think that solves it for Knut!
