similar to: "ACCTGMX" to "1223400" in R?

Hi, I'm try to collect a list of methods/packages available in R for doing in-string variable/symbol substitution, e.g. someFcn("pi=${pi}"), anotherFcn("pi=@pi@") and so on becomes "pi=3.141593". I am aware of the following: ** gsubfn() in the 'gsubfn' package, e.g. > gsubfn( , , "pi = $pi, 2pi = `2*pi`") [1] "pi = 3.14159265358979,

Using Ulrik?s example data (and assuming I understand what is wanted), here is what I would do: ex.dat <- c("FName: fname1", "Fval: Fval1.name1", "Fval: ", "FName: fname2", "Fval: Fval2.name2", "FName: fname3") tst <- data.frame(x = ex.dat, stringsAsFactors=FALSE) sp <- strsplit(tst$x, ':', fixed=TRUE) chk <-

I've had a bug/pessimization which I've tracked down for 1 bit bitmasks: if (((xx) & (1ULL << (40)))) return 1; if (!((yy) & (1ULL << (40)))) ... The second time Constant Hoisting sees the value (1<<40) it wraps it up with a bitcast. That value then gets hoisted. However, the first (1<<40) is not bitcast and gets recognized as a BT. The second

@Don your solution does not solve Vijayan's scenario 2. I used spread and gather for that. An alternative solution to insert mising Fval - picking up with Don's newtst - is newtst <- c("FName: fname1", "Fval: Fval1.name1", "FName: fname2", "Fval: Fval2.name2", "FName: fname3", "FName: fname4", "Fval: fval4.fname4")

Hi, I am working with a file (900MB in size) that has around 10 million records (in particular FASTQ records). I am able to read in the file as an object of BStringSet. When I start to manipulate the data, after almost 4 hours, I get the error message as Error: cannot allocate vector of size X.0 Mb (where X was once 160MB and then 180MB). The R version used is 2.11.1. I am not sure how to check

Hi Chris, If you have everything setup to test, can you generate the LLVM IR with -03 from 3.4.1 and 3.5 to be sure they match. Then we can focus on the backend.

Dear all, I am trying to calculate a score for a string sequence consisting of the following four letters: ACGT. I have got a matrix giving the scores for each pair of letters. So for example the string ACCT has got the pairs: AC, CC and CT. The matrix has got the following form: names<-c("A","C","G","T"); mscore<-matrix(0,4,4);

Currently in R, constructing a string containing values of variables is done using 'paste' and can be an error-prone and traumatic experience. For example, when constructing a db query we have to write, paste("SELECT " value " FROM table where date ='",cdate,"'") we are getting null result from it, because without (forgotten...)

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),

I am inserting a DNA sequence into a plot, and hope to colourize each of the four nucleotide of the DNA sequence with a unique colour i.e., A ("red"), C ("green"), G ("blue", and T ("yellow"). I use the following codes, but the DNA sequence only shows as "red" DNA <- "ACGT" plot(1, xlim = c(0,1), ylim = c(0,1), axes=F,

Buenas tardes, Tengo un problema al ejecutar un script de R desde la consola de Windows 8.1. El código desde RStudio funciona perfectamente, pero al ejecutarlo desde la consola peta al hacer una cambio de caracteres. El error que da en la consola es: Error in chartr("áéíóúà èìòùâêîôû", "aeiouaeiouaeiou", xpeliculas) : 'old' es más largo que

I was wondering if there is a way of editting strings in R. I have a set of strings and each set is a row of numbers and paranthesis. For example the first row is: (0 2)(3 4)(7 9)(5 9)(1 5) and I have a thousand or so such rows. I was wondering how I could get the corresponding string obtained by adding 1 to all the numbers in the string above. Dursun [[alternative HTML version deleted]]

Dear friends - I have a data.frame with "," instead of "." and found the discussion http://r.789695.n4.nabble.com/How-to-replace-all-commas-with-semicolon-in-a-string-tt4721187.html#a4721192 so copying the code of Ulrik(I hope:-)) I tried (making some data) AX <-

Hi Vijayan, one way going about it *could* be this: library(dplyr) library(tidyr) library(purrr) ex_dat <- c("FName: fname1", "Fval: Fval1.name1", "Fval: ", "FName: fname2", "Fval: Fval2.name2", "FName: fname3") data.frame(x = ex_dat) %>% separate(x, c("F1", "F2"), sep = ": ") %>% filter(F2

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",

Hi all, Does any one know of any encryption/decryption algorithms in R? I'm not looking for anything robust - I want some way of printing output to the screen that the user can't read immediately, but can decrypt a little later. The main thing I don't want to the user to see is a number, so (e.g.) ROT13 isn't appropriate. Hadley -- Assistant Professor / Dobelman Family Junior

R-2.0.0, WinNT / WinXP: options(chmhelp=TRUE) ?dnorm # does not work! ?Normal # works! Looks like calling compiled html help does not work for aliases, but only for the title of help pages...

Greeting R Community, I am a windows user so this problem may be specific to windows. I often want to source files from within R such as: C:\Users\Rinker\Desktop\Research & Law\Data\School Data 09-10. To source this file I need to go through the path and replace all the backslashes (\) with forward slashes (/). I usually do this in MS Word using the replace option, however, I'd like
