Dear Developers, Having spent time developing and thinking about how data aggregation and summary statistics can be enhanced in R, I would like to present my ideas/efforts in the form of two commands: The first, which for now I called 'collap', is an upgrade of aggregate that accommodates and extends the functionality of aggregate in various respects, most importantly to work with

R 3.4.2 OS X Colleagues I would appreciate some help with regular expressions. I have string that looks like: " ITERATION ,THETA1 ,THETA2 ,THETA3 ,THETA4 ,THETA5 ,THETA6 ,THETA7 ,SIGMA(1,1) ,SIGMA(2,1) ,SIGMA(2,2)? In the entries that

Hi Dennis, How about: # define the two values to search for x<-2 y<-3 # create your search string and replacement string repstring<-paste(x,y,sep=",") newstring<-paste(x,y,sep=".") # this is the string that you want to change thetastring<-"SIGMA(2,3)" sub(repstring,newstring,thetastring) [1] "SIGMA(2.3)" Use gsub if you want to change

You can either use positive lookahead/lookbehind - but support for that is a bit flaky. Or write a proper regex, and use backreferences to keep what you need. R > x <- "abc 1,1 ,1 1, x,y 2,3 " R > gsub("(\\d),(\\d)", "\\1.\\2", x, perl = TRUE) [1] "abc 1.1 ,1 1, x,y 2.3 " B. > On Feb 12, 2018, at 9:34 PM, Jim Lemon <drjimlemon at

Dear Sebastian, Initially I was a bit hesitant to think about yet another way to summarize data, but your illustrations convinced me this is actually a great addition to the toolset currently available in different R packages. Many of us have written custom functions to get the required tables for specific data sets, but this would reduce that effort to simply using the right collap() call. Like

gday R gurus, has anyone seen this lm problem? When I add 2 bytes to the variable name (via names), lm returns an error. It's as if there's a limit to the size of the variable names. Any suggestions? thanks, John Strumila > names(y)[12:14] [1] "Log.SQLServer.Locks.RID.Lock.Wait" "Log.SQLServer.Lock" [3] "xxaa"

Has anyone got vim to have syntax highlighting with R function codes? I know there's something similar that works with emacs (ESS or something like that), but I was wondering if anyone knew an equivalent that worked with vim.

Colleagues, =20 In using the paste command I have to spell out the collapse option: =20 > paste(1:3,coll=3D"a") [1] "1 a" "2 a" "3 a" > paste(1:3,collapse=3D"a") [1] "1a2a3" =20 My understanding is that the abbreviation coll should be adequate. Actually, even collaps isn't enough: =20

The last line gets duplicated when a file is read like this: a <- scan(file=filename, what="", sep="\n", strip.white=c(TRUE), quiet=TRUE) (This error does not occur on Linux, the only other platform I tested.) Version: platform = hppa2.0-hp-hpux10.20 arch = hppa2.0 os = hpux10.20 system = hppa2.0, hpux10.20 Actually, all binaries are

One gets a different response when abbreviating collapse= in paste? In the second case, it appears to be acting as if " + " is just another argument to be pasted. # expected response > paste(c("X","Y"),1:4,sep="",collapse=" + ") [1] "X1 + Y2 + X3 + Y4" # different! >

Hi everybody, just arrived at R and immediately I got a problem. Here's my script: setwd("C:/Users/Tom/Eigene Tools/Programming/R/Data") blast_hits<-read.table("blastHit_covLenght.txt", header=T) blast_hits <- as.matrix(blast_hits) numerical1<-data.matrix(blast_hits, rownames.force = NA)

R 2.15.1 OS X Colleagues, I encountered the following unexpected behavior today: The following command yielded the expected result: paste(c("TEXT1", "TEXT2"), collapse="|") Result: [1] "TEXT1|TEXT2" However, abbreviating "collapse" by even one character: paste(c("TEXT1", "TEXT2"), collaps="|") yielded the

I''m using rails to build some new functionality into an existing website and MySQL database system. I know there are ways to set up models to use the legacy tables and that I should be able to get the application to run properly with the DB in it''s current state. The problem that I am having is the database isn''t translating into a schema that can be inserted into the

HI, sorry but i don't understand how to make a function with as.function() formula<-"2+3*x" formu<-as.symbol(formula) > formu 2+3*x formul<-as.function(alist(x=,formu)) curve(formul,1,5,col="blue") Error in xy.coords(x, y, xlabel, ylabel, log) : x and y lengths differ > typeof(formul) [1] "closure" and not plot the curve function, Why?

Hi, I'm an R beginner and I'm struggling with what should be a rudimentary task. My data is along these lines: ID name1 name2 name3 name4 Class 0 1 0 2 Var1 A B C A Var2 B C C A Var3 C A B A etc. I'm using the following: foo <- data.frame(t(read.table("file", header=FALSE))) but of course now it's not using ID, Class, etc. as column names. As you can imagine,

Hi Everyone, I figured out this weekend that Ruby''s Thread implementation causes the Ruby/Event binding I wrote to completely stall and go dead. After reviewing the Ruby source and watching several strace runs, it''s clear that the Ruby Thread implementation uses select in a way that--while not being bad--just isn''t compatible with libevent. The second a thread is

Dear Everyone, I try to automatically manipulate the data of a variable (class = factor) like x 220 220a 221 221b B221 Into two variables (class = numeric) like x y 220 0 220 1 221 0 221 1 221 1 y has to carry the information about the class (number or string) of the former x-Variable. I could do it by hand like x[x == "220a"] <- 220
