Dear, I'm looking for some examples on OO programming in R. I have the programming manual with explanation on UseMethod and NextMethod but I miss some practical examples to get me going (I hope). I searched the web but could not find a good independent tutorial on this. Any suggestions are welcome, Kris -- ------------------------------------------------------------------------

Hi, I'm new to R and looking for a way to use a variable to reference to an object. I'm plotting several graphs on top of each other and want to do this by a for loop. The field I want to graph have names like a1,a2,a3, ... I can't figure out how to get this working: It should look like this: lines(spectral$Wavelength,paste("spectral$a",j,sep=""),col=j) but

Hi, I looked for the nls() function and couldn't find it. In the refman.pdf it's mentioned as part of the nls package which I cannot find and I also read something about the MASS package, also impossible to find for me.

Dear, we have a problem with geoR. We try to read an ASCII table (x,y,z) with 40000 lines. With read.geodata we get the error: Error in vector("double", length) : cannot allocate vector of length 799980000 We can read the file without any problem with read.table, but trying to convert it to the geodata class gets the same error. Any help/tips would be appreciated. Kris, Dave --

Hi, I can't figure out how to get the P-values out of the summery of a logistic regression. I used: logit.out <- glm(...) and then I should be able to extract just the P values for the coefficients. Any idea? Kris -- ------------------------------------------------------------------------ http://perswww.kuleuven.ac.be/~u0027178/VCard/mycard.php?name=krisn

Dear, I have XYZ data available in a MySQL database. I get it out, can plot the data with the plot() function, load it into a geoR datastructure. But what I actually would like to do is a simple contouring of the data based on a no Kriging interpolation such as TIN based. I know the first thing I shold do is interpolate a full matrix for the region I have my points for, then contour should

Dear all, Is there a simple trick to read in data with the following format and create a Time Serie object of it? Date CountOfField2 5/10/1998 7 5/11/1998 5 5/12/1998 2 5/14/1998 1 5/15/1998 1 5/19/1998 1 5/20/1998 1 5/21/1998 1 5/24/1998 2 5/25/1998 1 5/26/1998 2 .... 2002 ... R should recognize that some dates are not available...(NA). You can define start and end date Ok, and frequency= 365

Dear, Thanks for the previous tips about 'its' for importing the following data. 5/10/1998,7 5/11/1998,5 5/12/1998,2 5/14/1998,1 5/15/1998,1 5/19/1998,1 5/20/1998,1 1. When using the following command; test<-readcsvIts('Fires98.csv',informat=its.format("%m/%d/%Y"),header=FA LSE) the function reads in the data from the csv file as; V2 05/10/1998 7

Hi R-Helpers, I'm dealing with the STL procedure and trying to apply the tsdiag and StructTS onto the ts object to analyse the different parameters which need to be set. How can I use the tsStructure & tsdiag to create a seasonal, trend and cycle subseries plot so that I can select & analyse the correct np,ns, nt and nl? The problem is that too much signal goes into the seasonal

Dear R Helpers, Currently I'm working with the ts package of R and created a TimeSerie from pixels extracted from satellite imagery(S10 NDVI data, 10 daily composites). I'm trying to decompose this signal in different signals (seasonal and trend). When testing out the STL method is says => Only univariate timeseries are allowed, but the current Timeserie I'm using is univariate!

Hello all, I want to interpolate some data i prepared in GRASS, so I'm looking for what interpolation methods are available for R. In GRASS I can do Splines with tension and IDW. I'm looking for something like multiquadric equations. Is there any function/package available fo rthis? thanks all -- +-------------------------------------------------+ Carlos Henrique Grohmann de

Hi all, Does anybody of you have the winbond w6692 working with the mISDN/chan_misdn.so? When loading chan_misdn.so from Asterisk, I get a "No lower Id port:1" error. The /var/log/messages file says: "MISDN free_device: entitylist not empty" I'm using Linux 2.6.11.11 + mISDN-CVS-2005-05-01 + Asterisk 1.0.7 + Zaptel 1.0.7 chan_misdn build from chan_misdn-beta-0.0.3-rc6

I am having an issue with a windows app I installed. I am running wine 20050310 on kubuntu Edgy. Everything in the app seems to be functioning fine except com1. I am not able to access the hardware (microcontroller) via com1 at all. I checked the .wine/fake_windows/dos_driver/com1 shortcut and it exists. What can I do to fix this issue and get my software and linux to open com1? Thanks. --

Hello everybody, my company wants to integrate all Unix servers into active directory. For "normal" account management I decided more or less to go down the winbind route. To have all information in one place, we also want to put sudoers in the AD. Now the question is, how can I access the information ? I don't think, winbind can provide sudoers information. So, I guess I have to

Hello! One little problem when accessing Samba shares that require password authentication. I have WinXP. When clicking on the name of share in the Network Neighbourhood, I get prompt for password. But the user name field is greyed out and is preset to "guest". So I can't specify needed username. If I try to access password protected share created on some other Windows machine, then

Now that Rails core converts a database''s decimal type into a Ruby BigDecimal type, is it ok to now store money information as a decimal in the database (instead of an integer)? Joe

I have "time estimated" and a "time spent" fields in my task form. In my tasks table I have the "time_estimated" and "time_spent" rows assigned as float types. I''ve also tried setting them to decimal (4,2) with no luck. When I submit the form the error reads "NoMethodError in TasksController#create" then "Undefined method

Hello, When I am writing in sqldf or RSQLite I lose the decimals in my matrix. The only way I can get decimals is by multiplying by 1.00000, etc. I have tried manipulating the options, but it is only effective once I multiply by 1.0000. I appreciate any suggestions! Thanks! Example: z <- sqldf ("select ST, SUM(AGEP*PWGTP)*1.000000000/SUM(PWGTP)*1.00000000000000 as wgtage from ss09

Hello list, I'm just getting started with R, and I'm trying to determine how R treats large numbers that have decimals. Take the following two examples: > x <- c(999999999999999.9) > sprintf("%.5f",x) [1] "999999999999999.87000" > y <- c(9999999999999999.9) > sprintf("%.5f",y) [1] "10000000000000000.00000" I realize that I have

Hi, I'm trying to calculate some functions loop, unfortunately my data are decimal numbers that not allow me to get an accurate estimate. I do not want to use neither "round "nor "signif" but I would prefer to have all the information available, (the function loop is generic so you should adapt to all data, not just those in particular). The approximation error is
