similar to: replicate rows

Dear All, Probably a very basic question, but can't seem to work my way around it. I want to which row has the maximum value. But what if the row names do not correspond with the row numbers. In the example below, you'll see that the max of example is row 4, but the name of row 4 is "9". How do I get R to return "9" as value, instead of 4. example <-

Dear subscribers, I have made a simulation using loops rather than apply, simply because the loop function seems more natural to me. However, the current simulation takes forever and I have decided - finally - to learn how to use apply, but - as many other people before me - I am having a hard time changing habits. My current problem is: My current code for the loop is: distances <-

How come the k is 3 in all of this output? I expected it to be equal to r. > tmp3 <- lapply(1:3, function(k) function(r) print(paste(r, "<- r | k ->", k))) > for (i in 1:3) { tmp3[[i]](i) } [1] "1 <- r | k -> 3" [1] "2 <- r | k -> 3" [1] "3 <- r | k -> 3" -- Med venlig hilsen Rune Schjellerup Philosof Ph.d-stipendiat,

I often find myself making lists similar to this list(var1=var1, var2=var2) It doesn't seem list has an option, to make it use the name of the variable as name in the list. Is there another function that does this? -- Med venlig hilsen Rune Schjellerup Philosof Ph.d-stipendiat, Forskningsenheden for Biostatistik Telefon: 6550 3607 E-mail: rphilosof at health.sdu.dk Adresse: J.B.

Hello Railslist, I''m trying to get Gruff running on OSX Tiger (intel) with edge Rails. I''ve installed ImageMagick, Rmagick, FreeType and all their dependencies, or so I believe. (I''ve compiled them from source mostly, following a recent tutorial for Rails and ImageMagick on Intel Macs) While following the sample on the Gruff downloadpage (the one with the fruit), Rails

Hello R-help list,   I am looking for way to toggle the case of the characters like a flip-flop; that is from ''Hello'' to "hELLO" or vice versa.   I know that there are a number of functions like casefold, tolower, toupper, etc. but these functions change the case in an uniform way.   Thanks in advance,   Antonio Rivero Ostoic         Antonio Rivero Ostoic PhD Student,

Browse[1]> j <- c(1,2,NA) Browse[1]> j[j==1][-1] [1] NA Browse[1]> j[j==1][-2] [1] 1 Browse[1]> j[j==1][-2] <- 2 Error during wrapup: NAs are not allowed in subscripted assignments As far as I can see, I have no NA in the lhs (not after the second subscript anyway). Besides, I have a single value on the rhs, so it should be allowed to have NAs in the lhs, according to

Hello. I'm a visually impaired statistician, working at the National Institute of Public Health in Denmark. I would like to use R for some analysis and have succesfully installed version 2.13.0 on my Windows XP labtop. I then would like to run R interactively but unfortunately the textfont of the command line in the R window is very hard for me to read. I use a special program called

Hello R folks, Reproducible code below - I'm trying to do a weighted mean by a factor and can't figure it out. Thanks in advance for your assistance. Mike data<-data.frame(c(5,5,1,1,1), c(10,8,9,5,3), c("A","A","A","B","B"))

Dear R users, I have spent most of this day figuring out how to read STATA data into R (which eventually worked) and to run a simple OLS regression. It seems that the manuals are written in the most general and abstract way which does not really make it easy to understand what's going on. I'd be glad if somebody could save my day by: telling me how to define a matrix from the

Dear expeRts, I fail to succesfully pass strings to functions. It comes down to the observation that > plot(someVariable,anotherVariable) works fine, but > x <- "someVariable" > y <- "anotherVariable" > plot(x,y) does not. Does this have something to do with the returned value of x being /"someVariable"/ and not /someVariable/, i.e.

hi, I have to configure Xen server and DomU''s which should be able to talk to different vlans - depending on services put on DomU''s. I would like to enslave 2 NICs via bond interface. Both NICs are on trunk ports which are configured in the same way, the same native vlan. I don''t know, if I have to add vlans tagging to eth* interfaces then enslave tagged eth*

Hello, I'd like to transpose data to create an analysis-friendly dataframe. See below for an example, I was unable to use t(x) and I couldn't find a function with options like PROC TRANSPOSE in SAS.

Hi, I try to connect to a host that has IPv4 and IPv6, but IPv6 is currently blocked by ACL's. My host also has IPv6 and IPv4.

Hello Rails-list, I''m working on a CMS in Rails. The company that I work for currently uses a CMS written in PHP, and I want to mimick it in Rails, and improve along the way. The PHP variant works with templates like this: In the root of the webdir, there are the template files, named cms_news.html for example. This page contains custom tags, in the form of definitions and

Hello, The company that I work for will be developing a large webbased survey (for a government institution) somewhere in Q1/Q2 of 2006.

The survey application will have to perform under very high peak load, and the exact specifications of the hardware are not known at this point. I''m assuming
