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,

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

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 R-Experts, I have an empirical dataset with 150 subjects for 24 observations. In each observation, each subject can have a score in the range 0:3. I made then a simple index making the sum of the values in each row, so each subject have a score between 0 and 72. I was thinking about what kind of theoretical distribution such an index should have, so I try to make things random like:

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, 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 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

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

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

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, just a little question, I am interested in Latent Class Analysis and I guess if there is a package for this pourpose thank for you help, Simone

Dear list, can someone tell me why this two pieces of code give me the same results? > for(i in 0:5){ sum[i] = i } > sum [1] 1 2 3 4 5 > for(i in 1:5){ sum[i] = i } > sum [1] 1 2 3 4 5 shouldn't the first one be 0 1 2 3 4 5 thank you, simone

Hello List, I have a data frame like: V130 V131 V132 V133 V134 V135 V136 1 0 0 0.9 0 0.9 0 0 2 0 0 0 0 0 0.8 3 0 0 0 0 0.9 0 0 4 0.9 0 0 0 0 0 0.9 5 0 0 0 6 0 0 0 0.9 0 0 0.9 7 0 0 0.8 0 0 0 0 8 0.9 0 0 0.9 0.8 0 9 0 0 0 0.9 0.9 0 0 10 0 0 0 0 0 0 0.9

Dear list, I am trying to make eps file with embedded font. I use: postscript("ranking-exp-all.eps", horizontal=TRUE, onefile=FALSE, paper="special", height=8, width=12, family="Helvetica") # plot stuff dev.off() since R does not embed font, I then use: embedFonts(file="indegdistr.eps", outfile="indegdistrEMB.eps",

Hello List, I would like to simplify a data.frame like this columnA columnB user10 proj12 user10 proj19 user10 proj12 into something like: columnA columnB columnC user10 proj12 2 user10 proj19 1 I know unique() can simplify the data.frame, but how to count and store the duplicates? thanks in advance for any help. best regards, Simone

Dear List, is it possible to plot vertical labels under vertical bars? for vertical labels I mean to rotate 90 degrees horizontal labels I suppose yes, because if excel can do this, R should do it twice better... thank you, Simone

dear list, I have read a spss file with read.spss() now I have a list with all my variable stored as vectors. is it possible to selec cases based on the value of one or more variables? thank you, Simone

Dear List, I have this little problem: I work with adiacency matrix like: data me you me 0 1 you 1 0 I store those matrix in a mysql database actually I use RMySQL with: res<-dbSendQuery(connection, "SELECT * FROM table") myDataFrame<-fetch(res) to retrive the table, and I have data me you 1 io 0 1 2 tu 1 0 I would like the first column to be seen

hello R-Users, I have this simple but not for me question: I do: > res<-dbSendQuery(con, "SELECT * FROM tabellaProva") > myDataFrame<-fetch(res) > myDataMatrix<-as.matrix(myDataFrame[,-1]) > namerows(myDataMatrix)<-as.character(myDataFrame[,1]) and I have: io tu io "0" "1" tu "1" "0" my problem is that the
