I'm having trouble creating a looping variable and i can't see wher ethe problem arises from any hep gratfully appreciated First create a table x<-table(SURVEY$n_0,exposed) > x exposed False True Under 16 24 1 16-19 68 9 20-24 190 37 25-34 555 204 35-44 330 87 45-54 198 65 55-64 67 35 65+

Hi All, i have a dataset that i want to dynamically inspect for the number of variables that start with "Exposure_" and then for these count the entries across each case i.e ID Exposure_1 Exposure_2 Exposure_3 1 y y y 2 y y - 3 y - - So the corresponding new variables

Dear R helpers exposure <- data.frame(id = c(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20), ead = c(9483.686,50000,6843.4968,10509.37125,21297.8905,50000,706152.8354, 62670.5625, 687.801995,50641.4875,59227.125,43818.5778,52887.72534,601788.7937, 56813.14859,4012356.056,1419501.179,210853.4743,749961,6599.0862), pd =

Hi All, I have a questions about associative list mappings in R, and if they are possible? I have data in the form show below, and want to make a new 'bucket' variable called combined. Which is the sum of the control and the exposed metric values This combined variable is a many to many matching as values only appear in the file if they have a value > 0. conversion.type filteredID

Hi All, I'm trying to split my dataset, into multiple datasets that i'll analyse later, i wanted to do this dynamically as i might need to rerun the code later. I was looking at doing this via a loop, (Are other methods more appropriate? Would a function be better?) However i'm not sure in R how do do string replacement within the loop in order to create unique dataset names based on

I would like to identify _almost_ duplicated rows in a data frame.  For example, I might declare as duplicates pairs of rows that are alike at about 80% of their columns.  When working with tens of thousands of rows and upwards of 20 columns an iterative approach, testing all permutations, can be time consuming.  Duplicated() with incomparables sounds like the ticket.  But previous discussion in

Hello R Helpers, Business - 64 bit windows 7, R 2.11.1 I am trying to match the character contents of one list, called 'exclude', to those of a second list, called 'dataset' dataset is a list of file names with folder locations, and looks like this when called: > dataset [1] "A/10-10-29a-13.cdf" "A/10-10-29a-14.cdf" "A/10-10-29a-15.cdf"

Hi All, Newbie question for you all but i have been looking at the archieves and the help dtuff to get a rough idea of what i want to do I would like to merge two dataframes together based on a keyed variable in one dataframe linking to the other dataframe. Only some of the cases will match but i would like to keep the others as well. My dataframes have 67 and 28 cases respectively and i would

Estimados R-users: Estoy intentando usar la función 'agrep' para hacer búsquedas en cadenas de texto. El parámetro max.distance permite controlar la medida de aproximación de búsqueda de la función de Levenshtein. No obstante, cuando hago búsquedas específicas no obtengo siempre el resultado deseado y no se si es un bug o que no entiendo bien el algoritmo de búsqueda. Por

Hi All, I'd like to see the function code behind the barplots2() function in the gplots package, however i come across a bit of a stumbling block of a hidden function, can anyone help? > library(gplots) > methods(barplot2) [1] barplot2.default* Non-visible functions are asterisked > barplot2 function (height, ...) UseMethod("barplot2") <environment:

The documentation for agrep says it uses the Levenshtein edit distance, but it seems to get this wrong in certain cases when there is a combination of deletions and substitutions. For example: > agrep("abcd", "abcxyz", max.distance=1) [1] 1 That should've been a no-match. The edit distance between those strings is 3 (1 substitution, 2 deletions), but agrep matches

Happy new year everybody, I'm getting the following while trying to use the agrep() function: > pattern <- "XXX" > subject <- c("oooooo", "oooXooo", "oooXXooo", "oooXXXooo") > max <- list(ins=0, del=0, sub=0) # I want exact matches only > agrep(pattern, subject, max=max) [1] 4 OK > max$sub <- 1 # One allowed

Hi All, I'm trying to run nls on the data from the study by Marske (Biochemical Oxygen Demand Interpretation Using Sum of Squares Surface.

Another newbie question. I've written a function and saved the file as Xtabs.R, in a central place on a network so others will be able ot use the function, My question is how do i call this function? I've tried to chance the working directory, and tried to load it via; > library(Xtabs, lib.loc="//filer/common/technical/surveys/R_test") but neither seem to work? the function

Hi all. This is my first message at R-help...so I'm hoping I have some beginner's luck and get some good help for my problem! FYI I have just started using R recently so my knowledge of R is pretty preliminary. Okay here is what I need help with - I need to know how to use agrep in a for loop. I need to compare elements of a vector of names with other elements of the same vector.

Hi, I'm trying to get the --fuzzy option to work with --compare-dest with rsync 3.1.0. I'm testing with two files. "C_VOL-b001-i3818.spi" and "C_VOL-b001-i3816.spi" are copies of one another, but I've modified the latter a bit with a hex editor as a test. The modified date is still the same. This works for me (fuzzy is utilized against the 3816 test file): rsync

Hi, I'm having a problem trying to get the --debug flags to work with 3.1.0. I wanted to check with the mailing list to make sure this is really a bug and not something I'm misunderstanding. This is what I'm running (as a test): rsync --fuzzy --fuzzy -vv --debug=FUZZY,FUZZY2 C_VOL-b001-i3818.spi rsync://user at localhost/SHARENAME/dest The "dest" folder on the destination
