HI Sridhar, Try this: #I saved the file as .csv. ?testMaster<-read.csv("test1Master.csv") ?test2Sorted<-read.csv("test2Sorted.csv") testMaster1<-testMaster[order(testMaster[,1]),] test2Sorted1<-test2Sorted[order(test2Sorted[,1]),] Combinedat<-as.matrix(merge(testMaster1,test2Sorted1,by="X")) ?rownames(Combinedat)<-Combinedat[,1]

I believe the performance of isUnsorted() in sort.c could be improved by calling REAL() once (outside of the for loop), rather than calling it twice inside the loop. As an aside, it is implemented in the faster way in doSort() (sort.c line 401). The example below shows the performance improvement for a vectors of double of moving REAL() outside the for loop. # example as implemented in

Hi, I've read ?is.unsorted and searched. Have found a few items but nothing close, yet. Is the following expected? > is.unsorted(data.frame(1:2)) [1] FALSE > is.unsorted(data.frame(2:1)) [1] FALSE > is.unsorted(data.frame(1:2,3:4)) [1] TRUE > is.unsorted(data.frame(2:1,4:3)) [1] TRUE IIUC, is.unsorted is intended for atomic vectors only (description of x in ?is.unsorted). Indeed

Hi, In the man page for is.unsorted(): Value: A length-one logical value. All objects of length 0 or 1 are sorted: the result will be ?NA? for objects of length 2 or more except for atomic vectors and objects with a class (where the ?>=? or ?>? method is used to compare ?x[i]? with ?x[i-1]? for ?i? in ?2:length(x)?). This contains many incorrect

Hi, I am unable to build the letor module. I am generating the configure file using autoconf. The configure file generated is throwing the error ./configure: line 2057: syntax error near unexpected token `1.10.1' ./configure: line 2057: `AM_INIT_AUTOMAKE(1.10.1 -Wportability tar-ustar)` I am not too sure what to do with this. Need help with this. Thank You Regards Karthik On Mon, Sep 29,

Hi, Couldn't is.unsorted() bail out immediately here (after comparing the first 2 elements): > x <- 20000000:1 > system.time(is.unsorted(x), gcFirst=TRUE) user system elapsed 0.084 0.040 0.124 > x <- 200000000:1 > system.time(is.unsorted(x), gcFirst=TRUE) user system elapsed 0.772 0.440 1.214 Thanks!

Hi, I am C Karthik Iyer, a 3rd year B Tech student at NITK Surathkal. I am interested in working on projects on Information Retrieval and Machine Learning. I've had previous experience on working on projects regarding Question Answering Systems. I have a project idea which includes both IR and ML but i dont know how feasible the idea is. Could you guys say when will you be available

Guys, OK, now that we have the new core contributors squared away, we can go back to finishing the contributors list. There were some people who got added and then there is existing contributors list. I think Darren''s suggestion to wait to add new core contributors is fine (let the new constitution settle down and we can in the meanwhile have a more inclusive look at both rather than

Hi all, This must be such a beginner''s problem, but I can''t figure it out. I''m pulling two integers out of a database, and i want to divide one value with the other, but i keep getting an error about operating on strings. Here''s the code - low_freq = unsorted.last.freq high_freq = unsorted.first.freq divider = high_freq / low_freq In my view, if i display

I've just realized that it could be handy to have a 'decreasing' argument in 'is.unsorted'. And I'm cheekily hoping someone else will implement it. It is easy enough to work around (with 'rev'), but would be less hassle with an argument. The case I have in mind uses 'is.unsorted' in 'stopifnot'. Pat -- Patrick Burns pburns at pburns.seanet.com

The Letor project involves descent amount of Machine Learning while all the ranking related projects are around IR. Its better to introduce your idea on mailing list where all the mentors can have a detailed look at it, potential mentors can respond and the idea is kind of registered under your name.

Hi, I have started getting a hang of the xapian codebase. I think I would like to try my hands on the letor module of xapian. Could you please suggest some free data set for the training and testing of letor features.

When concatenating mbox files like described here https://xaizek.github.io/2013-03-30/merge-mbox-mailboxes/. You will end up with an 'unsorted' mbox file. Is this going to be a problem esspecially when they are large >2GB's and new emails will be written to it? The email client nicely sorts the message from folder A "foldera 5 last" as last, but of course the mbox is

Dear R users, I am looking for the source code of the implementation of ppr (Projection Pursuit Regression) in R. It will be great if citations of the source papers on which the implementation is based, are also provided.

Hi I am trying to understand what happen with the heatmap.2 code that it used to work (last used in October 2015). I am able to get a heatmap but my colour key doesn't come up and instead I get an error in all my files the used to work. Does anyone has any idea of what could have changed? or how to fix this. Thanks. # Error in seq.default(min.raw, max.raw, by = min(diff(breaks)/100)) :

I used successors to find the basic blocks that can be visited and those that cannot be reached. My pass just prints out those blocks which can be reached. The problem is that I want to include this in my compiler code rather than as a separate .cpp file which will perform the pass when I use 'opt'. I have seen that there is something called a PassManager class. Will this help me any way ?

Hi, Can someone tell me what was Gaurav Arora's exact contribution in the Clustering Search Results part during GSoC 2014? I guess that will be more helpful in understanding his code.

Referring to the log messages from my previous mail… I confused myself (and probably others) by reading the “Adding MemMgr 0x55555959f440“ message as “Registering MemMgr 0x55555959f440”. Thus the address mismatch made no sense. How could we be registering a `MemMgr` address/key that does not match once we arrive in `notifyObjectLoaded` method? Answer: Because the registrations is NOT coming
