similar to: c(), or cat(), or paste(), all cause unwanted reordering

I may be making a simple error, but I've looked at the str() of the resulting objects and I can't see any obvious reason I'm having the problem I am having, so I am reaching out to the R-help group. ?I am generating a string in my code. ?When I make a slight modification (add a comma at the end using my "lastcomma" function), I can no longer successfully write that string to

> a <- sqlQuery(irrdb, "select count(field) from mytable where field = 1") > print(a) count(field) 1 8 > paste(a) [1] "as.integer(8)" Why the as.integer() representation? I later pass the result into this write.html.table(), and what I get is rows of as.integer()... when all I want is the integer itself. as.integer(31) as.integer(21)

Yes I'd expect that too. But the **collapse** operation in paste() has never been about collapsing **multiple** character vectors together.

One gets a different response when abbreviating collapse= in paste? In the second case, it appears to be acting as if " + " is just another argument to be pasted. # expected response > paste(c("X","Y"),1:4,sep="",collapse=" + ") [1] "X1 + Y2 + X3 + Y4" # different! >

R 2.15.1 OS X Colleagues, I encountered the following unexpected behavior today: The following command yielded the expected result: paste(c("TEXT1", "TEXT2"), collapse="|") Result: [1] "TEXT1|TEXT2" However, abbreviating "collapse" by even one character: paste(c("TEXT1", "TEXT2"), collaps="|") yielded the

Totally agree with that. H.

Without 'collapse', 'paste' pastes (concatenates) its arguments elementwise (separated by 'sep', " " by default). New in R devel and R patched, specifying recycle0 = FALSE makes mixing zero-length and nonzero-length arguments results in length zero. The result of paste(n, "th", sep = "", recycle0 = FALSE) always have the same length as

How can I get a multi line string from a vector of string tokens in an easy manner (e.g. for the use as xlab of a plot)? I have e.g.: > tokens <- letters[1:5] [1] "a" "b" "c" "d" "e" I search: [1] "a, b, c\nd, e" I tried: > nlines <- 2 > ntokens.line <- ceiling(length(tokens) / nlines) > token.list <-

The 'recycle0' arg was added **after** the R 4.0.0 release and has never been part of an official release yet. This is the time to

Hello! s<-"start"; e<-"end" middle<-as.character(c(1,2,3)) I would like to get the following result: "start 123 end" or "start 1 2 3 end" or "start 1,2,3 end" How can I avoide this (undesired) result: paste(s,middle,e,sep=" ") Thank you! -- Dimitri Liakhovitski Ninah Consulting www.ninah.com

Hello, Is there a better way to use paste such as: a = paste(colnames(list.indep)[1],colnames(list.indep)[2],colnames(list.indep)[3],colnames(list.indep)[4],colnames(list.indep)[5],sep="+") > a [1] "aa+dummy1+dummy2+bb+cc" I tried a = paste(colnames(list.indep)[1:5],sep="+") > a [1] "aa" "dummy1" "dummy2"

Hello everyone, I've come up with a problem with using paste() inside apply() that I can't seem to solve. Briefly, if I'm using paste to collapse the rows of a data frame, AND the data frame contains strings with spaces, AND there are NA values in subsequent columns, then paste() introduces spaces. This only happens with that particular combination of data values and commands. I have

Hi, While reading about the new 'recycle0' argument of paste/paste0, I spotted a mysterious "cd" floating in the air in the man page: recycle0: ?logical? indicating if zero-length character arguments (and all zero-length or no arguments when ?collapse? is not ?NULL?) should lead to the zero-length ?character(0)?. cd ^^ This is in R

I was surprised by: > test <- matrix( as.character(1:4), 2) > test [,1] [,2] [1,] "1" "3" [2,] "2" "4" > apply(test, 1, paste, sep="+") [,1] [,2] [1,] "1" "2" [2,] "3" "4" > apply(test, 1, paste, sep="*") [,1] [,2] [1,] "1" "2" [2,]

Hello, I am writing this message because of an incorrect output by paste().

Hi, In the help file for str(), the following line appears: "no.list logical; if true, no ?list of ...? nor the class are printed". However, that appears to be true only on the top level; setting no.list to TRUE still leaves the remaining levels with the `list of ...' statement intact: > x <- list( + a = list(list()), + b = list(list()) + ); > str(x) List of 2 $
