Has anybody written an actuarial (life) survival procedure, this does not appear to be an option in the survival package? This approach is common in orthopaedic surgery to demonstrate the survival of prostheses. I need to apply the "modified" lower conf.int because of the censoring over time. I want a life table which I can then easily plot. Many thanks

Dear developeRs, I thought that backslashes can be escaped in the usual way (and I think I did this before) but I can't see why R> gsub("\\", "x", "\alpha") Error in gsub(pattern, replacement, x, ignore.case, extended, fixed, useBytes) : invalid regular expression '\' gives an error. Or am I just blind? Best, Torsten R> version

Hi, Some time ago I asked about how to use comma as decimal separator in plots and Mr. Paul Murrell wrote: ------- You could try something with axis() and chartr(), like ... par(mfrow=c(2,1)) plot(1:10/11, rep(1, 10), main="Standard X-Axis") plot(1:10/11, rep(1, 10), main="Customised X-Axis", axes=F) axis(1, at=pretty(1:10/11),

Hello everybody, this might be a trivial question, but I have been unable to find this using Google. I am trying to replace double backslashes with single backslashes using gsub. There seems to be some unexpected behaviour with regards to the replacement string "\\". The following example uses the string C:\\ which should be converted to C:\ . > gsub("\\\\",

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

Buenas tardes, Tengo un problema al ejecutar un script de R desde la consola de Windows 8.1.

I have been using the wonderful xtable package lately, in combination with Sweave, and I have a couple of general questions along with a more particular one. I'll start with the particular question. I basically have a 1x3 array with column names but no row names. I want to create a latex table with column setting set to "|rrr|". I want the column names to appear, but the

The following code works, to gsub single quotes to double quotes: line <- gsub("'", '"', line) (that's a single quote within doubles then a double within singles if your viewer's font is not good). But The R Language Manual tells me that Quotes and other special characters within strings are specified using escape sequences: \' single quote \"

Hello: I s there a way to use xtable with objects from the psych package, particularly principal()? Is there a difference between princomp and principal? xtable seems to play better with princomp.

I've been experimenting recently with the fantastic Sweave/xtable combination for generating latex. In the xtable vignette, I found this great example of printing a ts object by months. Is there a way to modify this code to generate RED numbers inside xtable for negative results in x.ts? Thanks in advance. - Ken # Sweave/xtable snippet below

Hello, I am trying to use the package "exams" to construct problem sets. I have constructed an exercise which generates a list of integers and asks the student to compute the median. rx is the vector of n numbers >str(rx) num [1:16] 21 9 8 18 4 12 17 2 9 7 ... I want to print out the entire vector as part of the problem. When I use \Sexpr(rx) only the first value (in this case

Hi all, Let me know if I need to ask this question of the bioconductor group. I used the bioconductor utility to install this package and also the CRAN package.install function.

Dear R community, is there any way to include a backslash in a charakter string without meaning some escape sequence? E.g. i need a string like: a <- '\hline' Error: '\h' is an unrecognized escape in character string starting "\h" to include some latex code in a xtable object, but I only mange to do: a <- '\\hline' which is not what I want.
