similar to: format integer numbers with leading 0

Dear R-er, I would like format integer number as characters with leading 0 for a fixed width, for example: 1 shoud be "01" 2 shoud be "02" 20 should be "20" Now I use: x <- c(1, 2, 20) gsub(" ", "0", format(x, width=2)) But I suspect more elegant way could be done directly with format options, but I don't find. Thanks a lot Marc

A simple question, but I can't find something to do what I want: Given: a vector of numbers, like lambda <- c(0, 0.005, 0.01, 0.02, 0.04, 0.08) Desired: format them in minimal space for use as plot labels, ie, without leading or tailing 0s. For this example: lambdaf <- c("0", .005", ".01", ".02", ".04", ".08") -- Michael

Hello, Can anyone help on gsub() in R? I have a string like something below, and wanted to delete all the strings with leading backslash, including "\xa0On", "\023, "\xab", and many others. How should I write a regular expression pattern in gsub()? I don't care how many characters following backslash. txt <- "Is This Thing\xa0On? http://bit.ly/jAbKem

Dear all, Is there a simple way to strip the leading "0"'s from R output? For example, I want Data <- data.frame(x=rnorm(10), y=x*rnorm(10), z = x+y+rnorm(10)) cor(Data) to give me x y z x 1.0000000 -.1038904 -.3737842 y -.1038904 1.0000000 .4414706 z -.3737842 .4414706 1.0000000 Several of you were kind enough to alert me to the existence of

all.vars works fine, EXCEPT, it give a bit too much. I only want the regression variables, but in the following example I also get "k" the variable holding the chosen knots. Any machinery to find only "real" regression variables? cheers, Bendix library( splines ) y <- rnorm(100) x <- rnorm(100) k <- -1:1 ml <- lm( y ~ bs(x,knots=k) ) mg <- glm( y ~

Under R-1.5.0 on Solaris 2.6: R> prettyNum(123456789, big.mark=",") [1] ",123,456,789" and that bad behavior (leading comma) spills into formatC as well: R> formatC(123456789, digits=0, format="f", big.mark=",") [1] ",123,456,789" Looks to me like a bug in src/library/base/R/format.R, in function prettyNum: B.[i.big] <-

All, I''ve found that the html view for the rspec formatter falls to pieces with Rails 2.02 and rspec 1.10. Has anyone else run into this trouble? Here''s a monkey patch that fixes the problem. A more elegant fix would be in order, but this gets the job done: Index: /Users/timcharper/www/exchange/vendor/plugins/rspec/lib/spec/runner/formatter/text_mate_formatter.rb

Hello I know that R's string functions are not as extensive as those of Unix but I need to do some text handling totally within an R environment because the target is a Windows system which will not have the corresponding shell utilities, sed, awk etc. Can anyone explain the following gsub phenomenon to me: >

I would like to extract the names, modes [numeric/factor] and levels of variables needed in a data frame supplied as newdata= argument to predict.glm() Here is a small example illustrating my troubles; what I want from (both of) the glm objects is the vector c("x","f","Y") and an indication that f is a factor: library( splines ) dd <- data.frame( D =

Hi I have this vector of strings. MyData <- c("Test1","Test2","I(Test1^2)","I(Test2^3)","I(Test1.Test2^2)") where I want to extract only the text after "I(" and before "^" so that the string returned only contain c("Test1","Test2","Test1.Test2") I am not very skilled in the use of matching

Dear R world, Do you know about a function that would capitalize in the correct manner first and family names? I found in the cwhmisc only the CapLeading function, but it just does not do the job, taking care only to capitalize the first letter of a word. I am looking for a function that would recognize " |'|Mc|-" and capitalize the first letter following these characters. An

Hi, What's the best way of dropping leading or trailing blanks from a character string? The only thing I can think of is using sub() to replace blanks with null strings, but I don't know if there is a better way (I also don't know how to represent the trailing blank in a regular expression). Thanks, Doug Grove

Hi there During execution of sapply I want to extract the number of times the function given to supply has been executed. I came up with: mylist <- list(a=3,b=6,c=9) sapply(mylist,function(x)as.numeric(gsub("[^0-9]","",deparse(substitute(x))))) This works fine, but looks quite ugly. I'm sure that there's a more elegant way to do this. Any suggestion? Christian
