Dear List, how can I coerce a matrix like this [,1] [,2] [,3] [,4] [,5] [,6] [1,] "0" "1" "1" "0" "0" "0" [2,] "1" "0" "1" "0" "0" "0" [3,] "1" "1" "0" "0" "0" "0" [4,] "0" "0"

Dear List, my problem should be easy to fix, but I couldn't find a solution by myself... In my survey, there is a question with 14 possible answers. None of the respondents choose the 13th answer, so when I table() the results, R says: 1 2 3 4 5 6 7 8 9 10 11 12 14 31 52 7 21 40 7 8 2 28 2 2 1 17 13 is missing... anyone knows how to tell table() that there are 14 modalities in the

Hi, I'm trying to determine the phase of irregularly sampled data. Is there any particular reason why both spec.pgram and spec.ls return phase<-NULL for vectors? Thank you.

Dear List, I'm looking for some documentation about the R tcltk package The one I found in the help doesn't look exaustive, I need information on the use of the single tk widget, maybe with some examples thank you, simone gabbriellini

Dear List, I have a data structure like: > aa [[1]] [1] 1 2 3 [[2]] [1] 4 5 6 > bb [[1]] [1] 3 [[2]] [1] 5 I would like to set differences between "aa" and "bb" and get as result another list of lists like: > res [[1]] [1] 1 2 [[2]] [1] 4 6 I am trying: lapply(aa, setdiff, bb) but I simply get "aa" back as result. Could you please point me in the

Dear R Fundation, I am a post-doc researcher at the University of Pisa, Italy. I apologize for my english and I have to tell you in advance that I am a very beginner with R. I used R for fitting dose-response curves (drc package) and for an ordinary ANOVA (one, two or three factors), including the post-hoc mean comparison (I used the LSD test...). Now I have to process some simple data on

The PC (Outlook) is accessing the mailbox via POP3, the iPhone is using IMAP; please consider we are talking about a user's home setup, so it's pretty difficult to have a more detailed report on his part (Outlook version, iPhone OS version, xDSL router type and configuration, etc.). The mail server 'dovecot -n' output is attached. The symptoms: when the Mail application is

Dear R-People, I am trying to measure distances between an empiric vector and two random vectors. Since one of the synthetic vectors has different length from the empirical one, I tried to introduce 0s to make all vectors have the same length, but this introduces a bias in the measurement. Since I have a lot of simulations of the two random vectors and I can boxplot them, I am thinking about

Hello List, I have some plots with the wireframe() function, and I'd like to display them in a single jpeg file. I know that par(mfrow=c(x,y)) will divide my display window in x rows and y columns, and although this works with plot(), it looks like it's not working with wireframe. here's my code: library(lattice) library(Cairo) CairoJPEG("wiley-rank.jpeg", width=960,

Hello LLVMers, as I have found in OCaML world, there comes the following event: Sixth International Conference on Coordination Models and Languages 24-27 February 2004, Pisa, Italy details: http://www.di.unipi.it/Coordination2004 P.S. I hope it is shouldn't be considered as off-topic here :-/ -- Best regards, Valery mailto: khamenya AT mail D0T ru

Dear List, I am using the wireframe function in the lattice package, and I am wondering if it is possible to invert the default axes orientation for x and y axes... what parameter should I look for? Best regards, Simone Gabbriellini

Dear List, I am trying to extend Rcmdr with some functions usefult to my study... I have addedd succesfully a menu and some submenu to the GUI, and I have placed a file .R in the /etc folder... I am able to call functions on that file, but I cannot see the results: how can I tell Rcmdr to write the output in the output box? Second question: how can I refer to the actually selected

Do anyone know anything about the use of R for agent-based social simulation? It should be possible, and would be convenient for the simple reason that there are several nice packages containing useful stuff for SNA (Social Network Analysis). Information about packages, web sites, experienced persons in the field, etc. would be very welcome. Tom

Hello List, I would like to connect to a postgreSQL database on a remote server and I am wondering what is the best package to do that. I have just installed RpgSQL, RPostgreSQL, Rdbi and RODBC. The handiest to me is RPostgreSQL but I don't see how to connect to a remote server with it. For sure I can connect to remote server with RODBC, but since I am on a Mac OSX 10.6, I have quite

Hello List, this should be simple, but cannot figure it out. I am trying to subset a data.frame like this: > data4 users time 1 user5 2009-12-01 14:09:58 2 user1 2009-12-01 14:40:16 3 user8 2009-12-04 08:18:37 4 user6 2009-12-04 08:18:37 5 user83 2009-12-04 08:18:37 6 user82 2009-12-04 08:18:37 7 user31 2009-12-04 08:18:37 8

dear list, I have problems with tkinsert I need to display a matrix as a result of my function, but when I use tkinsert(txt, "end", myMatrix, sep="\n") I simply obtain a string. I do: n<-tclVar() tclObj(n)<-matrix(data, ncol=lenght) tkinsert(txt, "end", tclvalue(n), sep="\n") any hints? thank you in advance, simone gabbriellini

I have no recollection of the original rationale for as.data.frame.table, but I actually think it is fine as it is: The classifying _factors_ of a crosstable should be factors unless very specifically directed otherwise and that should not depend on the setting of an option that controls the conversion of character data. For as.data.frame.matrix, in contrast, it is the _content_ of the matrix

Kevin, Maybe also look at what air quality monitoring is being done in area. https://cran.r-project.org/web/packages/RAQSAPI/vignettes/RAQSAPIvignette.html Depends what and how near, but might be something relevant there?
