similar to: function using values separated by a comma

Hi, I'm trying to replace all values equal to 1 in one file (a) with the value in the corresponding column in a separate file (b). Example below. Any help (and brief notes if poss) much appreciated. Thanks!! file a: 0,0,1,1,0 1,0,0,0,1 0,0,0,0,0 1,0,1,1,0 file b: 3,4,6,8,11 output request: 0,0,6,8,0 3,0,0,0,11 0,0,0,0,0 3,0,6,8,0 -- View this message in context:

Hi, I'm using the hist function to plot the frequency of 21 variables, but it keeps starting the x-axis from 0 and adding variables 1 and 2 together (all other vairables have the correct frequencies). I suspect it adds 1 and 2 together so that 0 can fit in with demarcations at intervals of 5. Using "xlim=c(1,21)" to specify that i don't want to include 0 and using the

Hi, I would like to replace all the max values per row with "1" and all other values with "0". If there are two max values, then "0" for both. Example: from: 2 3 0 0 200 30 0 0 2 50 0 0 3 0 0 0 0 8 8 0 to: 0 0 0 0 1 0 0 0 0 1 0 0 1 0 0 0 0 0 0 0 Thanks! -- View this message in context:

Hello, I have an example file which can be generated using: dat <- read.table(tc <- textConnection( 'T T,G G T C NA G G A,T A A NA'), sep="") I also have a reference file with the same number of rows, for example: G C A I would like to transform the file to numerical values using the following arguments: 1) Where data points have two letters separated by a comma, e.g.

Hi, I'm trying to generate a distance matrix between sample pairs (example below). I'm not very familiar with the loop command which I expect I will need for this. The example below demosntrates what I'd like to get out of the data - essentially, to calculate the proportion of positions where two samples differ. Any help much appreciated! Also, any notes on how the functions work

Hello, I would like to substitute a substring of characters defined by a specific start and end sequence. i.e. in the example matrix below, I would like to substitute ".:X:" with "", where X varies in sequence...   m<-matrix(c(".:0:0,0", ".:2:0,2", ".:194:193,1", ".:56:0,56", ".:58:50,8", ".:13:0,13", 

Hello; I am a R newbie and would like to know correct and efficient method for doing string replacement. I have a large data set, where I want to replace character "M", "b", and "K" (currency in Million, Billion and K) to millions. That is 209.7B with (209.7 * 10e6) and 100.00K with (100.00 *1/100) and etc.. d <- c("120.0M", "11.01m",

Dear R users, I am looking for more efficient way to compute the followings -------------------------------------------------------------------------- a <- matrix(c(1,1,1,1,2,2,2,2),4,2) b <- matrix(c(1,2,3,4),4,1) Eventually, I want to get this matrix, `c`. c <- matrix(c(1/1,1/2,1/3,1/4,2/1,2/2,2/3,2/4),4,2) --------------------------------------------------------------------------

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,

Hi, I don't know what I am doing wrong to the toupper does not seem working in sub + regex. The following returns 's' not the upper class 'S' as I expect: sub("q_([a-z])[a-zA-Z]*",toupper('\\1'),"q_sviRaw") Can someone tell me where I did wrong? Thanks, Richard [[alternative HTML version deleted]]

Hello, The code below works fine up until I try to use the "IN" statement in the last line. The proper SQL format is: SELECT * FROM this_table WHERE this_column IN (1,2,3,4,5) But, I think I may be getting something like: SELECT * FROM this_table WHERE this_column IN c(1,2,3,4,5) Which makes no sense in SQL. I think it may be just a matter of string massaging, but I'm not

Dear All, When one loads certain packages, some other dependent packages are loaded as well. Is there some way of detaching them automatically when one detaches the first package loaded?

Dear R users, I would like to draw map and import it in maptools/spatstat packages. The 'raw data' I have come from a web page (<map>...</map>) and are basically a list of coordinates of a polygon.

Hi all, Does anyone have a version of strsplit that keeps the string that is split by. e.g. from x <- "A: 123 B: 456 C: 678" I'd like to get c("A:", "123 ", "B: ", "456 ", "C: ", 678) but strsplit(x, "[A-Z]+:") gives me c("", " 123 ", " 456 ", " 678") Any ideas? Thanks,
