Hi, Would there be a function and/or some options to force R to write a value of say 1.0e-4 as "0.0001"? More specifically I want to use R to write ASCII file(s) for other programs to read and some of these programs don't know how to deal numbers in scientific notation or have a different convention. Thanks in advance. Yves Gauvreau B.E.F.P. Universit? du Qu?bec ? Montr?al cyg at

Hi, I have a 3 by 2 plots per page, and would like to place a legend on the last region. How to do that ? Also, is there any way to specify scientific notation for axes label ? [[alternative HTML version deleted]]

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,

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?

Hi, I was working on a project for my class and I am trying to make sure the y-axis numbers NEVER convert automatically to scientific notation. Is there anything I can set in the plot function to make sure of this? I know formatC( ) can be used in the axis function, but it seems to give me an error when using it in the plot function. Thanks, student-in-need-of-some-help

Hi I have a data.frame with the following numbers (first column are month numbers) 07,0,0,0,0.315444056314174,0,0,0,12.5827462764176,0.079194498691732, 0.0280828101707015,0,0.0695808222378877 08,0,0,105600,0.393061160316545,0,0,0,8.95551253153947,0.0880023174276553, 0.285714285714286,0,0.0669139911789158 09,0,0,0,0,12.5,0,0,13.5135887094281,0.0557531529154668,0,0, 0.0487526139182026

R developers, Seems I get a bad result ("%#4.0-1e" in particular) when trying to use prettyNum digits=0 with scientific notation. I tried on both my Linux box and on an online R evaluator and saw the same problem, so it's not limited to my box at least. I see the problem in both R 3.5.3 and R 3.3.2. options(scipen=-100) prettyNum(1, digits=0) [1] "%#4.0-1e" prettyNum(2,

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

Hello, Firstly, real new to R here. I have a function intended to evaluate the values in columns spread over many tables. I have an argument in the function that allows the user to input what sequence of tables they want to draw data from. The function seems to work fine, but when the user inputs a single number (over 9) instead of a sequence using the : operator, I find an error message: the

FWIW, it doesn't seem to be happening on Mac OS: > format(2^30, digits=0) [1] "1.e+09" > prettyNum(12345.6, digits=0) [1] "1.e+04" A glibc misfeature? -pd > On 22 Mar 2019, at 10:10 , Martin Maechler <maechler at stat.math.ethz.ch> wrote: > > Thank you, Robert for raising this here ! > >>>>>> Robert McGehee

If I knew this, I have forgotten it: Is there a way to force R to forgo use of scientific notation, e.g. to use .000029 instead of 2.9e-05? (Aside from using formatC for example) I run across this every now and then and work around it (multiple values by 100, for example) but cannot find any way to deal with it otherwise. A particularly problematic place it pops up is in axis tick labels.

Hi All, I'm trying to create labels to plot such that it doesn't show up as scientific notation. So for example how do I get R to show 1e06 as $1,000,000. I was wondering if there was a single function which allows you to do that, the same way that as.Date() allows you to show in date format on a plot.

Hi, How can I format numbers to engineering notation? That is, like scientific but where the exponent is always a multiple of three. Some examples: 1635 000 000 => 1.635E9 163 500 000 => 163.5E6 0.000 000 000 135 => 135E-9 I've tried format and formatC but I couldn't get them to work they I want. Any help is greatly appreciated. Thanks, Sam

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, When I run the following code, I cannot see the entire number. As opposed to seeing 1,000,000,000. I only see 000,000 because the rest is cut off. The cex option doesn't seem to be doing anything at all. y<-seq(1e09,5e09,1e09); plot(1:5,y,ylab='',yaxt='n' ); axis(2, at=y, labels=formatC(y,big.mark=",",format="fg"),las=2,cex=0.1); Any thoughts?

I could not find a way to specify the border color of the boxes drawn in a legend, so that the legend can match exactly the colors of the actual plot (e.g. in the case of two superimposed histograms which have different shading and different borders). Indeed, the legend function seems to hard code the color "black" for the borders in this call: rect2(left = xt, top = yt +

Hi (If you're wondering, this is a Project Euler question :)) If I wanted to calculate the sum of the digits in the decimal representation of 2^1000, what would be a good way to go about that? I've tried the following methods: # Calculate the sum of digits in the decimal representation of 2^n # Only works for smaller values of n bsum <- function(n) { s <- 0 e <-
