Hi, I am trying to find m breakpoints of a linear regression model. I used the segmented package. It works fine for small number of predicators and breakpoints.(3 r.v. 3 points). However, my model has 14 variables it even would not work even for just one breakpoints!. The error message is always estimated breakpoints are out of range. Since my problem is time related problem. So I

Hi all, I'd like to use the Hmisc::summarize function, but it uses a function (FUN) of a single vector argument to create the statistical summaries. Consider an easy case: I'd like to compute the correlation between two variables in my dataframe, grouped according to other variables in the same dataframe. For exemple, consider the following dataframe D: V1 V2 V3 A 1 -1 A 1

Hi R-Helpers: I?m trying to fit the same linear model to a bunch of variables in a data frame, so I was trying to adapt the codes John Fox, Spencer Graves and Peter Dalgaard proposed and discused yesterday on this e-mail list: for (y in df[, 3:5]) { mod = lm(y ~ Trt*Dose, data = x, contrasts = list(Trt = contr.sum, Dose = contr.sum)) Anova(mod, type = "III") } ## by John Fox or for

Hi all, I'm looking for a function with the same functionalities as Hmisc::summarize but accepting a dataframe as input (not just a vector or a matrix). I'd like to compute the correlation between two variables in my dataframe, grouped according to other variables in the same dataframe. For exemple, consider the following dataframe D: V1 V2 V3 A 1 -1 A 1 1 A -1 -1

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'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

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 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.

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.

Hello I haven't found an example on how to compare the value of a string variable with spaces in it, and the While loop below never exits: ========== extensions.conf exten => start,n,Set(MYVAR="Dummy value") exten => start,n,NoOp(${MYVAR}) ;BAD TOO ;exten => start,n,While(!$[${MYVAR} : "Some string"]) exten => start,n,While($[${MYVAR} != "Some

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 %> ... <%

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 have a list (call it 'mylist') with the following elements: (i) a function (call it 'myfunc' and expressed as 'mylist$myfunc') and (ii) a variable (call it 'myvar' and expressed as 'mylist$myvar'). Since I use mylist as a pseudo-class (I assign mylist to multiple different R objects), I would like to access the mylist R object from within the

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: >

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

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 >

Dear all, I would like to point to a minor bug in the documentation of merge(). The documentation (?merge) says all logical; all = L is shorthand for all.x = L and all.y = L. I think the correct description should be all logical; all = T is shorthand for all.x = T and all.y = T. The source file which needs to be fixed is src/library/base/man/merge.Rd To be sure that it hasn't been fixed
