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 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(0.5999...

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=&...

[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: > >>>>&g...

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 type 'character.' cand_receipts[,1] <- formatC(cand_receipts[,1], width = 5, format...

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, 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]]

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 jus...

...ans to me with leading 0s, so that the PNGs become easy to navigate in a file/image browser. Lacking a better solution I ended up using the code below, but would much prefer something like png("test_%d.png",bg="white",width=1000,height=700) where %d could be formatted like formatC(%d,digits=0,wid=3,flag="0",mode="integer") Thank you, b. #---works, but is rather complicated--- pngno <- 0 ; i <- 1 for (w in 1:53) { if (i %in% c(4*0:100+1)) { pngno <- pngno + 1 png(paste("test_",formatC(pngno,digits=0,wid=4,flag="0",m...

Dear R-Help members, I have a question about how to save to the hard drive the one thousand datasets I generated in a simulation. The datasets are created in a "for" loop that repeatedly creates normally distributed datasets, such as the example below: Library(MASS) for (number in 1:1000) { dataset = mvrnorm(n = 400, mu = c(0,0,0), Sigma =

In a string context, grep, gsub, sub are improperly treating NA (missing) as the string "NA", and returning unexpected results > grep("A", c(NA,"NA")) [1] 1 2 # expected: # [1] 2 > gsub("A", "X", c(NA,"NA")) [1] "NX" "NX" # expected # [1] NA "NX" > sub("A", "X",

...#39;m having problems doing this in a speedy way. The simplest solution (calc_history below, using apply, paste and collapse) takes about 2 seconds for a 10,000 x 10 matrix. I thought perhaps paste might be building up the string in an efficient manner, so I tried using matrix multiplication and formatC (as in calc_history2). This is about 25% faster, but still seems slow. smp <- matrix(rbinom(100000, 1, 0.5), nrow=10000) calc_history <- function(smp) { apply(smp, 1, paste, collapse="") } calc_history <- function(smp) { mul <- 10 ^ ((ncol(smp)-1):0) as.vector(formatC(s...
