similar to: Pretty printing numbers

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

Dear list, I'd like to report a bug in `prettyNum()`. When called with a numeric vector, the `replace.zero` argument is disregarded. > prettyNum(0, zero.print = "- ", replace.zero = TRUE) [1] "-" Warning message: In .format.zeros(x, zero.print, replace = replace.zero) : 'zero.print' is truncated to fit into formatted zeros; consider 'replace=TRUE' A

Thank you, Marttila and Ivan, As the original author of prettyNum() {etc ..}, I will commit such a bug fix to R-devel (and probably port it to R 4.5.0 patched) quite soon (but not yet today).

Thanks for the contribution Mikko! For testing future patches, you can actually do it right in the web browser, thanks to Heather Turner's R Dev Container, see instructions here https://contributor.r-project.org/r-dev-env/container_setup/ Best Toby On Mon, May 26, 2025 at 6:28?PM Martin Maechler <maechler at stat.math.ethz.ch> wrote: > Thank you, Marttila and Ivan, > > As

Tim, The purpose of the `replace.zero` argument is to allow longer replacements. See for example the behaviour with a character vector input: > prettyNum("0", zero.print = "- ", replace.zero = TRUE) [1] "- " I'm pretty sure this is a bug, and have now posted the relevant details on r-devel. A fix would be below. Best, Mikko diff --git

I managed with success to export a data frame of 367 columns and 37 rows to a txt file, but unfortunately I couldn't manage the same with the transposed data frame. Specifically, it seems like the notebook cannot "read" correctly 367 columns, so it reads the first 145 columns and it folds down the rest of them and consequently it folds down the respective data.

Hi all, I want to label an axis with exponents, but can't get it done with expression. Any hints would be very welcome! # simulated data, somewhat similarly distributed to my real data: set.seed(12); d <- rbeta(1e6, 0.2,2)*150 ; d <- d[d>1e-8] hist( d? , breaks=100) # now on a logarithmically scaled axis: hist(log10(d), breaks=100, xaxt="n") abline(v=

Hi all; I need to create ASCII files as output from R and I'm using sink(), cat(), and paste() for this. My problem is that the ASCII files hace several columns, and I would like to know if intermediate columns (the second one for example) could be alineated to the right. My values are integer ranging from 1 to 1000. Thanks a lot. Best regards, Javier

I have two pairs of related vectors x1,y1 and x2,y2 I wish to do a test for differences in means of x1 and y1, ditto x2 and y2. I am getting odd results. I am not sure I am using 'pt' properly...

You fed it two characters, "dash" and "space" and it only wanted one character so it truncated to the first character and warned you that that's what it did. If you had your space before the dash, it would have used that as your replacement character > prettyNum(0, zero.print = " - ", replace = TRUE) [1] " " Warning message: In .format.zeros(x,

I frequently use an S-Plus function print.char.matrix for printing boxed tables. I use LaTeX even more frequently, for which I (and Rich Heiberger) have a series of functions that will be in the Hmisc library in R before too long. [I have seen some other interesting functions for latex already in R.] But it would still be nice to have an equivalent of print.char.matrix in R for ordinary

Is it possible to get a line number with an error report? I have a long script and an error: Error in `[.xts`(x, xsubset) : subscript out of bounds It would be very helpful, and save a lot of time, if there was some indication in the error message which line the error was. I can find it using binary search but that is a painful process. cheers Worik [[alternative HTML version deleted]]

I think I am whistling in the wind, but is there a modern symbolic debugger for R programmes? I am working through some one else's code, thousands of lines, that has the occasional bug in it, and a lot in my understanding of it. I cannot make setBreakpoint or findLineNum work. I get "No source refs found.". I am starting to loose my mind! A debugger where I could set
