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

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,

Full_Name: Dirk Jacob Version: R 2.8.1 and 2.9.1 OS: Win XP Submission from: (NULL) (153.96.32.62) I want to convert numbers to strings like: > inputs= c(0.3+0*(1:12) ) > (format(inputs,digits=3,scientific=T,collapse=" ")) and it works [1] "3e-01" "3e-01" "3e-01" "3e-01" "3e-01" "3e-01" "3e-01"

Hi! If I use format() on numeric vector, na.encode argument does not have any e= ffect. This was reported before: - https://stat.ethz.ch/pipermail/r-help/2007-October/143881.html - http://tolstoy.newcastle.edu.au/R/e2/devel/06/09/0360.html It works for other (say character) classes! > format(c("a", NA), na.encode=3DTRUE) [1] "a " "NA" >

Hi I am using the latex() command from the Hmisc package to export table to latex. For formating of the values, I use the format() function. But I don't manage to get the format of the values right: I don't want scientific notation, but if I say scientific=FALSE, I get many digits after the decimal point which I can not control with digits=... and nsmall=... in the format command.

R gurus, Every so often(*) someone asks how to suppress scientific notation in printing, so I thought I'd give it a shot, but I need some help. The formatting decision is made(**) on line 286 of src/main/format.c : if (mF <= *m) { /* IFF it needs less space : "F" (Fixpoint) format */ where mF is the number of characters for "normal" printing and *m is the number

Hi, I am troubled by the use of NULL or NA to indicate missing/non-specified function arguments. In the R code that I have looked at, it seems that both forms are used (NULL seems to be used more often though). Sometimes both variants are in the same declaration, e.g. format.default <- function(x, trim = FALSE, digits = NULL, nsmall = 0, justify = c("left",

Hello All I am having a bit of trouble formatting my HTML with the desired number of digits after the decimal place. Am I doing something wrong/misunderstanding or is it a bug? Looking at the example supplied with ?HTML.data.frame: HTML(iris[1:2,1:2],nsmall=c(3,1),file="") Gives html output that includes the lines: </tr> <tr><td

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

Hi, I have a text (.dat) file, in which each row contains several long numeric strings. One of the strings is 38 digits long, for example: 03200801200801172008011720092904008901 When I read in the data file, this string shows up as 3.200801e+36. To get rid of the scientific notation, I used "options(scipen=999)." When I did this, the scientific notation went away, but the numeric

Hello, helpeRs, I have a vector of numbers from 1-365 (days of the year) that I would like to convert to a date. There are no NA's and no missing values. I did not insert leading zero's for numbers less than 100. Using the syntax: dat$doy.1 <- as.numeric(format(dat$doy, "%j" )) I get the following error message: Error in prettyNum(.Internal(format(x, trim, digits,

Hello group, I have a data frame called test.df with a bunch of columns. When I do a print(test.df), I want the numbers to appear a pre-defined setting. I believe this can be achieved by sprintf but this needs to be done individually for the data. However, is there an option that I can set so that all numerical values default to comma separated, 2 decimal places when they appear? Thanks, S

Hi everyone, I can't figure out how to format numbers to have a certain number of significant figures (as opposed to decimal places) without using scientific notation and including trailing zeros if necessary. e.g. I would like to achieve the following: 0.800001 ---> 0.8000 123.4567 ---> 123.4 0.1234567 ---> 0.1234 7.654321 ---> 7.654 7654321 --->

Hi! I'm an R newbie and this should be a trivial problem, but I can't make it work and cannot find what I'm doing wrong in the literature. I entered the the command: table<-data.frame(x, scientific=F, digits=4) table This prints a column of x with 16 useless decimal places after the decimal point. Also, it prints an unwanted index number (1-20) in the left column. How do I get rid

I came to report this same bug and found it already in the trash, but I slightly disagree with that assessment. If it's not a bug, then perhaps it's a feature request. Comments at the end.

Dataframe cust has Date-type column open.date. I wish to set up another column, with (first day of) the quarter of open.date.

How to force R to print 2 decimal places in column of a data.frame? I tried to do so: x = inp(format(rounf(inp$Tamanho, 2), nsmall = 2),) where "INP" is data.frame and "Size" is the name of column.
