The code below is a small reproducible example of a much larger problem. While the script below works, it is really slow on the true dataset with many more rows and columns. I'm hoping to get the same result to examp, but with significant time savings. The example below is setting up a data.frame for an ensuing regression analysis. The purpose of the script below is to appends columns to

...c(1,10,100,2,20,200,3,30,300,4,40,400) value2=c(1.1,10.1,100.1,2.1,20.1,200.1,3.1,30.1,300.1,4.1,40.1,400.1) example<-data.frame(mydate=mydate,value1=value1,value2=value2) example$group<-c(rep("group1",3),rep("group2",3),rep("group1",3),rep("group2",3)) exampe$group<-as.factor(exampe$group) ### Generating variable names with spaces: names(example)<-c("mydate", "my value 1","my value 2","group") ### Trying to aggregate - but it's not working. Clearly, my reference to variable names is incorrect: mynames&...

...ue but I have unable to find the answer for it either in the R-manual or by browsing the web. I would like to know if there is a "mode" function in R, such that from a vector or matrix the function returns the most common value. In other programs I use (such as Matlab) I can have for exampe a 3X3 matrix A, A=[1 2 3; 1 3 2; 3 3 2] and I can find the mode of the rows so that mode(A[1:3,:]) returns a 1X3 matrix [1 3 2]. Is this possible in R as well? If not, how would one go about this? Thank you very much, Bill [[alternative HTML version deleted]]

...rototype.js et al, i am currently creating a sortable list with: Sortable.create(''id'', { onChange: myFunc }); but what i really want is an event that occurs after the li''s have been reordered and settled into the new list order. how would i do that? i know i can do for exampe: Event.observe(''id'', ''mouseup'' , func , false); i''m sure there''s a very simple solution, it''s just escaping me, thanks for any tips. -brent -------------- next part -------------- An HTML attachment was scrubbed...

Hi, Dear LLVMers I just touch llvm source code for several days, and I didn't know the interfaces of the analysises and transformations of LLVM. For exampe, how to backtrace CFG, and whether exits a backtracking interator to do such work? For a novice, I also seek for suggestions about how to become familiar with LLVM interfaces as soon as possible. Now I have a plan to write a pass based on LLVM, and my first challenge is how to make the best use of...

...all, I have a problem with computing a new variable as an aggregated score of other variables. Say, I have 10 variables for 1,000 observations (people). Every variable may have values between 0 and 8. What I would like to do is computing the mean of the individual top 3 values for every person. Exampe: The values for the 10 variables (v1 to v10) for person A, B and C are as follows: A 0 1 0 2 5 8 3 0 4 0 B 6 4 3 0 0 0 0 5 0 0 C 0 0 8 0 0 8 0 0 0 0 So, I would like to compute a new variable for the mean of the individual top 3 values, which would result for person A, B and C in the following:...

...BSS section. My idea is to split the uninitialized global variables in two sections and to aggregate them depends on the uses of each variable at execution time (by profiling I will know what variable will be in each section). In addition, can I add more address spaces for heap and stack also? For exampe, can I split my stack in two segments, one to hold critical info like return address and frame pointer, and another to hold function arguments? How I can do it?

Hello! I am running a loop. The result of each run of the loop is a data frame. I am merging all the data frames. For exampe: The dataframe from run 1: x<-data.frame(a=1,b=2,c=3) The dataframe from run 2: y<-data.frame(a=10,b=20,d=30) What I want to get is: merge(x,y,all.x=T,all.y=T) Then I want to merge it with the output of the 3rd run, etc. Unfortunately, I can't create the placeholder for the overall r...

Hi I would like to use arima () to find the best arima model for y time series. The default in arima apparently is to use conditional sum of squares to find the starting values and then ML (as described on the help page). Now using the default may lead to error messages saying: "non-stationary ar part in CSS". When changeing the default to "ML" only the minimization

There is a fairly new bug in wilcox.test in R-2.2.1 (stable). It wasn't there when I last taught nonparametrics in fall 2003. Line 86 of wilcox.test.R achieved.alpha<-2*psignrank(trunc(qu),n) It should be achieved.alpha<-2*psignrank(trunc(qu)-1,n) If you don't see why, decode the cookbook instructions p. 56 in Hollander and Wolfe (2nd ed.) or see

Hi, Are there any plans to "export" the documentation from time to time(e.g. at releases) from the WIKI in an "offline" form to be usable as printed, and/or to be distributed with into scriptaculous-js-1.x.x.zip ? It is very uncomfortable that the ZIP distribution contains practically no documentation :(. Most of the WIKIs have such export function (many of them even export

...of WinBUGS14), and WinBUGS cannot calculate it, but this is allowed in WinBUGS. If I just ran it in WinBUGS, that would be fine, because my goal is to get the summay not DIC, but I need to run it in R, and R must have DIC. (the example as follow).
