Hi, I have the following: for(j in (y.raw+1):(rownum-1)){ valsum<-tstfframed[min.x,j]+tstfframed[min.x,j+1] if(valsum == 1){ cat("valsum loop") int.num<-int.num+1 } } but I get the error message: "Error in if (valsum == 1) { : argument is of length zero". I checked whether to see if all the stated variables have associated values (and are not NAs) and

Hello, I have searched for documentation on the function contourLines's algorithm but cannot find a thing. I am about to submit a paper to a journal but cannot yet do so because I need to provide some reference for this function. Does anyone know what algorithm is used for this function?

Hi, I am inquiring as to what are the best practices with respect to storing and manipulating ordered multi-dimensional arrays. For example, suppose I have a sequence of time-varying covariance matrices of asset returns. The data is ordered, but the ordering is not necessarily regular (e.g. daily data omitting weekends and holidays, etc.). The data array is say, N x N x T. For example, the

Hello from a neophyte! Is there a diagnostic programme which can be run to determine if there are any faults in Samba 2.2.3a? I cannot connect from Win XP to my rev/b iMac (suddenly, maybe 'upgrade' to 10.3.4 had some effect) and the smb crashlog (shown below) has a pile of stuff which is incomprehensible to me. Secondly, how does one upgrade to another version of Samba and is this

I've just started using R and am still a neophyte, but I found the following curious result. I'm using the current version of R (2.5.1 (2007-06-27) ). Why are the results for the third quartile different in the output from the summary and fivenum commands? For the following data set 457 514 530 530 538 560 687 745 745 778 786 790 792

The US water year extends from 01 October yyyy-1 through 30 September yyyy and is referenced by the year starting on the included 01 January yyyy. I'd like to be able to find the annual means for the water year. To do so I've taken the input date-time, which is in the usual format "1991-10-07 10:35:00" changed it by: w$d<-as.POSIXct(w$date.time) Now I can add an

Dear R community, I am a neophyte and I cannot figure out how to accomplish keeping only the first record for each ID in a data.frame that has assorted numbers of records per ID. I studied and found references to packages plyr and sql for R, and I fear the documentation for those was over my head and I could not identify what may be there to reach my goal. If someone could point me toward a

I'm trying to write a small function (below) to compute Box & Cox transformations of x for arbitrary values of lambda. I'd like to specify a range of values for lamba (min,max,step) and am having trouble getting the for loop to work. Suggestions? Any pointers to resources for learning to write functions in R for neophyte programmers? Thanks. --Dale boxcox <-

Back in 2009 there was some discussion of the practicality of supporting char sizes greater than 8-bit: http://lists.cs.uiuc.edu/pipermail/cfe-dev/2009-September/thread.html#6349 http://lists.cs.uiuc.edu/pipermail/llvmdev/2009-September/thread.html#26025 with the consensus seemingly being "quite doable, please get a good patch and submit". However the current code appears (to my

I have a list of polygons generated by the contourLines() command (each object of the list is a list in itself with two objects: a vector of x values, and a vector of y values for each vertex). I wish to convert that list into a gpc.poly object of multiple contours. How do I do this? gpclib apparently has no method of coercing lists into the gpc.poly object type. As well, when I have a

Dear list members, i am trying to get ldap + samba + kerberos working and have tried to make the proper configuration. Integrating samba + ldap was pretty easy, but getting kerberos to work seems a nightmare.

Does anyone know of a R package that will determine the convex hull of a high-dimensional dataset (say 4-10 dimensions). I know chull works for 2D data. I'm neophyte to R and convex hulls so please keep it simple. Many thanks Ben -- Ben Stapley. Biomolecular Sciences, UMIST, PO Box 88, Manchester M60 1QD. Tel 0161 200 5818 Fax 0161 236 0409

Hello, I wanted to figure this out myself, but sadly I can't. I started Tinc under XP/SP1, it worked great. I wanted to make a change in the config, so I went to the services control and stopped Tinc. Now when I go to start it I get this error: No Windows tap device found!. Yet, I see a tap device in 'Device Manager' and in 'My Network Places'. It works fine under

Hello, I have data in a frame: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 I would like them arranged in a single column: 1 2 3 4 . . 8 9 . . 16 etc. I believe this should be possible using reshape, but I can't see how to do it. Thanks for sparing time to help a neophyte, Roger Mason

Greetings Supreme Council of R Masters, Like toddler, I have gotten my head stuck in the banisters of R ... again. Let it be know I am still a neophyte in the R-community forum world, so please don't flame me too bad. I have two sets of data, each with a set of timestamps. I would like to somehow merge the datasets based on the timestamps and an individual identifier. That is there are

Hello, I'm ashamed to admit that I'm an R and meta-analysis neophyte just when my colleagues and I are attempting to run R for that latter purpose. We would like to construct a graph of the 95% confidence intervals of odds ratios (inverse odds ratios, actually). We are using the metaplot() function in the "rmeta" package. While we can construct a basic plot, we cannot configure

Dear List: I am very much a unix neophyte, but recently had a Ubuntu box installed in my office. I commonly use Windows XP with 3 GB RAM on my machine and the Ubuntu machine is exactly the same as my windows box (e.g., processor and RAM) as far as I can tell. Now, I recently had to run a very large lmer analysis using my windows machine, but was unable to due to memory limitations, even after

Hi All, I have to say upfront that I am a complete neophyte when it comes to programming. Nevertheless I enjoy the challenge of using R because of its incredible statistical resources. My problem is this .........I am running a regression tree analysis using "rpart" and I need to run the calculation repeatedly (say n=50 times) to obtain a distribution of results from which I will pick
