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"

Very few computer programs do that. You cannot `require' two digits by options(digits=2): ?options says digits: controls the number of digits to print when print- ing numeric values. It is a

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?

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"

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

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

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() >

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.

Dear R Core Team, First of all, thank you for your amazing work on developing and maintaining this wonderful language. I just stumbled upon the following behavior in R version 3.6.0: format(9.91, digits = 2, nsmall = 2) format(9.99, digits = 2, nsmall = 2) yield "9.91" and " 9.99" with an extraneous whitespace. My expected output for the second command is

I can reproduce this. It has to do with whether the value rounds down to 9 or up to 10, and thus needs another space, I think. I agree that it shouldn't happen, but at least you can get rid of the space by using trim = TRUE. # rounds to 9 vs 10 format(9.95, digits = 2) format(9.96, digits = 2) format(9.95, digits = 2, nsmall = 2) format(9.96, digits = 2, nsmall = 2) format(9.95, digits =
