similar to: split() - unexpected sorting of results

Thanks, for the explanation. Still, I think this is surprising bahaviour which might be handled better.

Hello, In order to solve that problem of sorting numerics made characters there is package stringr, functions str_sort and str_order. library(stringr) set.seed(2447) x <- sample(11L) sort(as.character(x)) [1] "1" "10" "11" "2" "3" "4" "5" "6" "7" "8" "9"

Hi! I'm developing R packages and use Travis CI for continous integration. When submitting to CRAN Im suggestet to test the package using the latest R-devel. I would like that all test where run using Travis. Is there anyone who knows if this is possible to run travis test using the latest r-devel? -- Regards M?ns ============================ M?ns Magnusson 070 - 588 97 15 mons.magnusson

Hello everyone, I have a couple of fairly simple questions (I hope) the answers to which I cannot find through the documentation at the moment. 1. I would like to delete the a row from a matrix if a certain elimination criterion is met. I am familiar with x <- x[-7,] (to remove row 7, for example). Are there any other means of removing an entire row? 2. Is there a single command that

Dear Timo, Posted this originally to the squirrelmail list but they said that sorting is done server side so concluded I needed to talk to you: ============= I feel there is an error in the logic of the sort by From column. If you sort by this column, the messages are re-ordered in alphabetical order using the *email address* as the sorted word. However most people these days have their

Hi I'm using R 2.0 in SuSE 9.2. When I plot data as a boxplot, the boxes appear on the plot in alphabetical order (of group) rather than the order in which they appear in the data. So far, the only thing I can do to fix this is to prefix the group labels with a,b,c...etc to trick R into plotting them in the right order. Can sorting be turned off? How should I address this sensibly? Thanks

Dear R colleagues, consider my data.frame named "df" with 3 columns - being level, prevalence and sensitivity - and 7 rows of data (see dump below). df <- structure(list(level = structure(1:7, .Label = c("0", "1", "10", "100", "1010", "11", "110"), class = "factor"), prevalence = structure(c(4L, 2L, 3L,

Hello, I have been using the TM package to create a TermDocMatrix, which I have saved as a matrix so that I can view word frequencies. Below is a section of the code that I have used and an excerpt of the output: What I wanted to be able to do is to view the output alphabetically - rather than the results being sorted by frequency as below, that an alphabetical list would be generated. This

Hello everyone, I am trying to prune a data frame for partial least squares analysis. I need to delete an entire row if one cell in the row contains a NA. Presently, I am running a loop that is supposed to extract the rows that are full of numbers into a second data frame and skips the rows that contain a single NA value. I want to know if there is a simple way to determine if a row

I have a dataset relating the effects of engineering works on the level of salinity in a river before and after the works. I have modelled this using linear mixed effects models to determine if the significance and level of the response to the works. I am wanting to calculate the se of difference at several points. I am not sure of how to calculate the difference and which estimate of se I

Hi i have a column in my ferret model called sponsored. It is a boolean and i want to order the results by sponsored and date registered. At the moment it is not managing to sort the booleans. I tried declaring this in my model but it seems to have had no effect. def false.<=>(o) o ? -1 : 0 end def true.<=>(o) !o ? 1 : 0 end I''m using the acts_as_ferret plugin. below

Since reports received over the interrupt pipeline are a recurring problem for various types of UPS'es, I propose to simply ignore the data we receive there and only flush the respective report buffer. By doing so, at the time the interrupt reports are processed the first variable that is retreived will trigger a poll for the corresponding feature report and we should be fine. The impact on

This has been dogging me for a while. I've started making a lot of tables via xtable so the way I want to sort things is not always in alphabetical or numerical order. As an example, consider I have a dataframe as follows set.seed(100) a <- data.frame(V1=sample(letters[1:4],100, replace=T),V2=1:100) I know I can sort the columns first by V1 first and then by V2 by: sorted.a <-

Hi, How do I use the string content of a string variable to reference a data frame of the same name? I want to do the typical tasks of 1) building a name with a string variable and using the string variable to create a data frame (or any object) whose name is the string value of the variable and 2) pass on a string to a function as a parameter, and then use that string to refer to an existing

Hi everybody, given a fresh rgui.exe load on winxp OS, I enter (a minimal exaple) n <- 12.357531 Then the following command: n <- (n - floor(n))*10; n gives the following outputs: [1] 3.57531 [1] 5.7531 [1] 7.531 [1] 5.31 [1] 3.1 [1] 1 === still as expected [1] 10 === not expected, count with me: 1 - floor(1) is zero, times 10 gives 0, not 10!!!! [1] 10 === should
