Currently as the first column in a data frame I have string values in the format xx_yy - I want to create a new column with just the substring xx (for each row in turn). Three possible ways to do this might be (1) split the string by '_' using strsplit and paste the first of the resulting variables into a new column, but I have been unable to do this for each row of my data frame in turn

Dear all, Please suggest me how can I do it. I have a matrix which look like following: x1 x2 x3 t1 .01 0.3 0 t2 0 0.1 0.01 t3 0 .01 .01 t4 0 0 t5 5 0 0 t6 0 0 0 t7 0 0 0 t8 0 0 0 t9 0.6 0 0 t10 0 0 0.66 t11 0 0.6 0.11 t12 0 0.4 0 I want to sort decreasing order in each column based on rows. and then to display only those rows which has a value. The expected out put matrix will

Hi, Trying to compile one of the latest snapshot tarballs of R-devel gives me the following error (64-bit openSUSE 10.3): ... make[2]: Entering directory `/loc/home/biocbuild/bbs-2.4-bioc/R/src/library/Recommended' make[2]: *** No rule to make target `VR.ts', needed by `stamp-recommended'.

Dear all, I have encountered some strange things when creating lm objects in R: model depends on the order of the terms specified in a formula. Let us consider the following simple example: > dat <- expand.grid(A = factor(c("a1", "a2")), + B = factor(paste("b", 1:4, sep="")), + rep = factor(1:2)) >

I'm trying to create a new column in my data.frame where subjects are categorized depending on values on four other columns. In any other case I would just nest a few ifelse statements, however, in this case i have 4*6*2*3=144 combinations and i get weird 'context overflow' errors. So I wonder if there is a more efficient way of doing this. For illustrational purposes, let's say

Hello, I?m hoping you have a few minutes to help out someone very new to R. I?ve done some searching, but cannot find this particular issue. I have survey data from two different time periods (years). Both years are stratified samples and have the same variables (and variable names), but are different people in the community answering in the different years. Everything loads into the survey

I still wonder if this would be an issue in _standard_ (not thin) LTO? This test seems to be OK on my (slightly modified) standard LTO flow, but I do wonder for a more general case.

Hello, I have a variable created like ... Set(__myVar=${ARG1}) ... Set(__${myVar}STATUS=) If ARG1 is abcd, variable is abcdSTATUS and should be empty. This is OK. Now I would like to get the value of abcdSTATUS. How to do it? ${${myVar}STATUS}} isn't working, nor ${{myvar}STATUS} Thanks for any hint -- Daniel

Dear all, When porting my package to WinXP I have the following problem: I need to create an environment variable "MYVAR=c:\mypath" which I have saved in the control panel "System->My Computer" (under the `Advanced' tab). I have two files which need to access MYVAR: config.win, Makefile.win While "config.win" does recognize MYVAR correctly,

I am trying to create a set of vectors which have similar names. They have a common part and an extra unique part. I am sure I have seen questions on this before but I have been unable to find it in the archive. There are examples of sets of names for columns of a data frame, but not for individual vectors. Suppose I want vectors named myvar.1 myvar.2 etc. I tried: >

I encountered an issue with ThinLTO handling of inline assembly, where the inline assembly referenced a constant that was a local variable. The local var was renamed because it was promoted in ThinLTO mode, but the inline assembly copy was not renamed and we ended up with an undef at link time. It looks like this is a general problem with inline assembly and LTO. Wondering if it is a known issue.

Can one create a variable through a function by name createVariable <- function(name) { outputVariable = name name <- NULL } after calling createVariable("myVar") I would like to have a variable myVar initialized with NULL in my environment. Is this possible? Ralf

This is a bit of a nuby question methinks but i''ve had a play/search around and it''s just bugging me now :0) Say I have a conditional statement, testing a variable against a number of values. The first way i did this is like so: if myvar != "" and myvar != 0 and myvar != nil # .. code end This seems a bit messy - is there neater way of doing this? I thought of:

Hi, I''ve got a problem when using templates in Puppet. In my node declarations, i set (or not) some special variables to activate (or not) some part of my configuration. When i don''t need the configuration part, i don''t declare the variable. I then use something like this in my templates: ... <% if defined? myvar %> ... myvalue = <%= myvar %> ... <%

Please guide me how to use those two methods. I can''t differentiate them. I was doing something on my model and I have put one field in the attr_accessible method. After that when I try to run the app the app always says my other fields are blank, but they''re all filled up. What''s wrong with it?

I hope you are doing well. For me, this was an unexpected problem. I've hoped for quite a few wrong things today, but I'm only asking you about this one. Why does ifelse(1, list(a, b, c), list(x, y, z)) return a list with only a, not list(a, b, c) as I hoped. I wish it would either cause an error or return the whole list, not just the first thing. Working example: > x <- 1 >
