similar to: small bug in formatC?

Full_Name: Bernd Bischl Version: 2.8.1 OS: Windows XP Professional Submission from: (NULL) (129.217.207.95) Hi, there seems to be a small bug in formatC: formatC("foo", format="s", mode="charcacter") Error in formatC("foo", format = "s", mode = "charcacter") : 'mode' must be "double" ("real") or

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

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

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

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,

formatC() is great for formatting numbers! But it would be even better if it could optionally insert commas (or semicolons), e.g. R> formatC(1234567.89, digits=2, format="f", commas=T) [1] "1,234,567.89" Here's a snippet of code that does that, which could more or less just be inserted into at the end of formatC if any R-core guru were so inclined. "r"

Hi, I've been playing around with the APFloat class lately and I came across behavior I was not expecting based on reading the implementation comments and I'm wondering if it's a bug or intentional. The behavior concerns converting an APFloat to a string and back again. In the implementation of ``APFloat::toString(...)`` you can specify ``FormatPrecision`` as 0. The method comments

We've had this more general topic on R-help, and also in R-devel recently. There's one case here where I get the feeling R never gets into swapping but more directly aborts possibly from a bug we can more easily fix. Today I've been working (successfully! - not yet committed) at fixing str() for very large strings. In this process, I've found that pc <- function(.)

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

[This turned into a bug report which will go to r-devel, so I have taken it off r-help.] Bugs reported here: (1) formatC's help page need some clarification. (2) formatC needs to treat modes "double" and "real" as equivalent. (3) format's help page or (preferably) format needs correction re the meaning of `digits' On Sun, 28 Feb 1999, Martin Maechler wrote:

Hi, What's one way to convert an integer to a string with preceding 0's? such that '13' becomes '00000000013' to be put into a string I've tried formatC, but they removes all the zeros and replace it with blanks Thanks -- Regards, Anh Tran [[alternative HTML version deleted]]

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

Some days ago, there was a discussion about the command formatC(exp(1),digits=100,width=-1) Converting a double value to a string, from which the double may be reconstructed exactly, may be useful. So, I did some experimentation with it in my linux installation of R-2.5.0. I generated a vector x of a large number of random doubles (random sign, random mantissa with 53 significant bits and

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

Dear R-Developers, Just a note: there are some inconsistencies between formatC(), format() and format.char() and cross calling between these functions. On the one hand > cat(format('{"}'), "\n") {\"} > cat(format.char('{"}'), "\n") {\"} is by default format.char(, flag="-") and thus by default calling format() >
