similar to: RE: Adding a line in the graph of 'plot()'

Hi. I'm a student at Simon Fraser University in British Columbia, Canada. I can't for the life of me figure out how to plot a 3D surface (A 3D response surface to be more specific) in R. I found your email address on a web board, and saw someone mention wireframe(), but using the help in R yielded no results. Any suggestions? Thanks. Dean Vrecko

Hello. I'm looking for a way to add a line in a plot of a points that should lie along a particular line. Can I add a line to the 'plot()' function, maybe using 'abline()' so that the line is visible in the graph of 'plot()'? How? More generally, can I overlay plots over one another? Thanks.

Hi. I'm a student at SFU in Canada. The basic thing I want to do is calculate means of different strata. I have 2 vectors. One has the values I want to take the means from, the other is the four strata I am interested in. So I essentially want to break up the information vector into the four strata and calculate four means, one for each stratum. How can I do this in a reasonable way? Thanks

Hi. I'm a student in a graduate program at Simon Fraser University in Canada. I am trying to run a simple screening experiment with some simulated data. I simply want to do an ANOVA of an experiemnt with 5 factors (4 have 2 levels, the last has 3 levels) and 48 runs (ie, full factorial). The thing is that I have multiple observations for each level combination (run). So, 1) How do I do

Yes and no. Given your response it appears that "Proper Case" is not a term that everyone uses. In Excel there is a function "Proper" which in essence changes "this line into something like this" into "This Line Into Something Like This." My look at casefold seesm to be that is is a wrapper of two functions to change text into either Lower or Upper case.So

I am probably just looking in the wrong place. I am sure there are a number of ways to do this. If anyone could point me in the right direction it would be very much appreciated.

I am trying to create a new variable which uses the suburb names if HR and HRRES are the same but which uses HRRES if they are different. Any assistance would be appreciated as my brain has just packed up. I'm not sure I can teach myself anymore new tricks this afternoon. HR HRRES SUBURB What I am trying to get 954 Wheatbelt

I am probably missing something quite obvious, but any help would be appreciated. I am continually getting people misreading the lattice plots because they are expecting the strip (with the factor names in them) to be below the graph. Is there anyway of achieving this. Secondly, from a more personal note I find the grid formed by the axes to be a bit overpowering and would like to make it a

Talking about Excel, you can produce excellent graphs in Excel. Yes you have to work at it, but you can get there. The problem is that they are not the default. My gut feeling is that R will make more of an impact in the presentation of graphics than any implementation in Excel. So even if a patent were granted and it made itself into a mainstream package, would it change the world or would the

I thought it would be quite simple to generate a number of sequences, but my only answer is to loop and this doesn't seem in keeping with R's capabilities. In short I have the start and finish positions of several (well thousands probably) sequences. So I am looking at how do I take x <- c(2,6,13,20) y <- c(4,10,16,24) and produce a list with four components with the appropriate

I don't normally have to go anywhere near this stuff , but it seems to me that this should be a straight-forward process in R. For the purposes of this enquiry I thought I would use something I can work out on my own. So I have my matrix and the right hand results from that matrix tdata <- matrix(c(0,1,0,-1,-1,2,0,0,-5,-6,0,0,3,-5,-6,1,-1,-1,0,0),byrow = T,ncol = 5) sumtd <-

The question puzzled me at first, because of your use of "library". It looks as if the hdf5 r "package" utilises the "windows hdf5 library" binary. My reading is that you will have to compile the package yourself after you have downloaded the hdf windows dll from hdf.ncsa.uiuc.edu The instructions are in win.readme.txt of the package source which you can download at

I would suggest that you make a more thorough search of the R-Archives. (http://finzi.psych.upenn.edu/search.html) If you do you will find this discussion has been had several times and that the type of machine you are running will have an impact upon what you can do. My feeling is that you are going have to knuckle down with the documentation and understand how R works and then when you have

I have some data that is dwarfed by one large cluster. I came across a paper titled "A New Partitioning Around Medoids Algorithm" (van der Laan, Pollard & Bryan, 2002) http://www.bepress.com/ucbbiostat/paper105/ that describes PAMSIL and PAMMEDSIL that look as though they might be more appropriate for the data I have. There does not appear to be much out there which is describing

I'm currently looking to interconnect my Asterisk PBX system with the PSTN via a digital PRI/T1.
