Under R-1.5.0 on Solaris 2.6: R> prettyNum(123456789, big.mark=",") [1] ",123,456,789" and that bad behavior (leading comma) spills into formatC as well: R> formatC(123456789, digits=0, format="f", big.mark=",") [1] ",123,456,789" Looks to me like a bug in src/library/base/R/format.R, in function prettyNum: B.[i.big] <-

I sent a message to <r-announce at stat.math.ethz.ch> last Thursday ("New package: colSums"), and still haven't seen it echoed on r-help or on the web archive (in fact there is no r-announce web archive for 2002). Is something broken? Did I need to use <r-announce at lists.R-project.org> instead? -- -- David Brahm (brahm at alum.mit.edu)

I have a Date x Stock (223 x 520) matrix of "trading volume". I can calculate a 5-day (past) average in about 1 second using: R> apply(vol, 1, filter, filter=c(0, rep(1/5,5)), sides=1) I would like to do the same with a 5-day median, e.g.: R> mymed <- function(x, n=5) { R> r <- rep(NA, length(x)) R> for (i in (n+1):length(x)) r[i] <- median(x[i-(1:n)]) R>

In R-1.5.0pre (2002-04-08) on Solaris 2.6, the window that X11() creates has a title like: R Graphics: Device 2 (ACTIVE) o iyeP )( y except the funny characters at the end have umlauts and other accents (i.e. extended ASCII characters), and they may be different each time X11() is invoked. There is no loss of functionality; it just looks a little ugly. I saw this behavior in R-1.3.?, it

Hi all After posting what follows, Duncan Murdoch suggested perhaps a bug in formatC, or an error on documentation. Any comments? In particular, bug, error or not, any ideas about how I can consistently get two significant figures to print? P. ---------- Original Message ---------- Hi all I am not a C programmer, but I am trying to understand formatC to get consistent printing of

As a sequel to my previous mail on cut, formatC does not produce what I have been taught is significant digits: > x <- c(1.0793,1.0796, 11.0954, 11.0736 ) > formatC(x,digits=3,format="g") [1] "1.08" "1.08" "11.1" "11.1" (3,3,3,3) significant digits OK > formatC(x,digits=3,format="f") [1] "1.079"

Hi all I am not a C programmer, but I am trying to understand formatC to get consistent printing of reals to a given number of significant digits. Can someone please explain this to me? These first three give what I expect on reading ?formatC: > formatC(0.0059999, digits=2,format="fg",flag="#") [1] "0.0060" > formatC(0.59999,

I do not know if this is a bug or a case of improper documentation. The documentation for formatC() implies that the difference between the options format="f" and format="g" is that with "g", scientific format is sometimes used. There is another difference between them that is not mentioned in the documentation. drop0trailing=FALSE is ignored when format is set to

I have a four-digit string I want to convert to five digits. Take the following frame: zip 2108 60321 60321 22030 91910 I need row 1 to read '02108'. This forum directed me to formatC previously (thanks!) That usually works but, for some reason, it's not in this instance. Neither of the syntaxes below change '2108' to '02108.' The values in cand_receipts[,1] are of

Hi, Search through the R archives, and couldn't find my answer... how do you format numbers with commas (standard American, one every three digits)? Thanks, Matt -- It is from the wellspring of our despair and the places that we are broken that we come to repair the world. -- Murray Waas

Perhaps this toy example will help: ## example data output <- list(1:5, 1:7, 1:4) lens <- lapply(output, length) maxlen <- max(unlist(lens)) outputmod <- lapply(output, function(x, maxl) c(x, rep(NA, maxl-length(x))), maxl=maxlen) outputmat <- do.call(cbind, outputmod) write.csv(outputmat, na='') The idea is to pad the shorter vectors with NA (missing) before converting

I'm using the following code to create quartile intervals of my dataset and it is working like it is suppose too. In my final output of the data I would like currency amounts to be displayed with commas. I have not found an option either through FormatC or sprintf that will display the data with commas, they only seem to add decimals. Is there a format that will display commas without me

I'm trying to convert a matrix of capture occasions to format that an external program can read. The job is to basically take a row of matrix, like > smp[1,] [1] 1 1 0 1 1 1 0 0 0 0 and convert it to the equivalent string "1101110000" I'm having problems doing this in a speedy way. The simplest solution (calc_history below, using apply, paste and collapse) takes about 2

formatC(0.0001, digits = 3, format = "f", zero.print="< 0.01") Error in strrep(" ", nc - i1) : invalid 'times' value The problem, if it is one, is in .format.zeros: .format.zeros("0.000", "xxxxxx") Error in strrep(" ", nc - i1) : invalid 'times' value R version 3.5.1.

Hello, A small problem I can't solve > p <- 0.0001 > p [1] 1e-04 How can I force the printout of p to 0.0001? I have tried 'format', 'round', 'signif', 'print' in different combinations without success. Fredrik Lundgren

Hi there, i'm not getting along with the following problem. I'd like to print a real number, e.g. x <- 12.3 with exactly two digits after the decimal point, e.g. 12.30 I've tried the whole format(), formatC() and prettyNum() functions but did not have any success with it. This should work with all real numbers, in case even with 0.0 (-> 0.00). For cracks this thing is pretty

Hello R-helpers, I have a problem with formatting a single number to show leading zeros. For example, I want "2" displayed as "002". My numbers have 1 to 3 digits and I would like them all to display 3 digits for printing. I know I could use "paste" in a loop with several "if"s, but I was wondering if there is a single function that can do this. I have
