similar to: set the bahavior that R deal with missing values?

as.integer() truncates doubles toward zero, as Splus does (at least v. 6.1 under Windows does). Thus: > look <- (10 * seq(14)) - 76 > 10 * (73.1 + look) [1] 71 171 271 371 491 586 681 791 886 981 1101 1201 1301 1401 > as.integer(10 * (73.1 + look)) [1] 70 170 270 370 490 586 681 791 886 981 1101 1201 1301 1401 ... It is not documented in R! I propose appending

Hi all, In R, is there some functions or ways to create a Clustered-Stacked Column Chart as the example in the following page http://peltiertech.com/Excel/ChartsHowTo/ClusterStack.html? I have browsed the R Graph Gallery (http://addictedtor.free.fr/graphiques/) and searched the R site, and didnot find an appropriate method to do it. Anybody has met this problem before? Thanks a lot.

Hello, I have many hundred variables in my longitudinal dataset and lots of missings. In order to plot data I need to remove missings. If I do > data <- na.omit(data) that will reduce my dataset to 2% of its original size ;) So I only need to listwise delete missings on 3 variables (the ones I am plotting). data$variable1 <-na.omit(data$variable1) does not work. Thank you

Dear Rusers, I have some data in .csv file like "2004-8-1" and "2004-10-1", and i need to convert them into days from the origin (January 1, 1960). I have tried the function date.mmddyyyy(), but cannot get it. Anybody can show me how to handle the date data? Thanks very much! My dataset like: time 2004-8-1 2004-10-1 2001-9-1 2002-9-1 -- With Kind Regards,

Dear Rusers, My question is about "recode variables". First, i'd like to say something about the idea of recoding: My dataset have three variables:type,soiltem and airtem,which means grass type, soil temperature and air temperature. As we all known, the change of air temperature is greater than soil temperature,so the values in those two different temperaturemay represent different

Dear Rusers, The error for the following was that it cannot allocate the vector of length 1920165909. a <- expand.grid(se1=0:100/100, sp1=0:100/100, se2=0:100/100, sp2=0:100/100, DR=0:100/100) How to solve it? Maybe setwd(dir) can, i am not very sure about it. Any ideas about it? [[alternative HTML version deleted]]

Dear Rusers, My manuscript has been conditionally accepted recently. The problem to generate the high resolution figures in R for the manuscript cannot be solved by me. The journal editor ask me to generate the figures with a minimum resolution of 500 dpi. I have tried the *menu-driven method* to save the figures as JPEG (100% printed quality), but the results seem not to be very good. I have

Dear all, I want to see the source codes for "dchisq(x, df, ncp=0, log = FALSE)", but cannot find it. I input "dchisq" in the R interface, and then enter, the following message return: > dchisq /*****************************************************/ function (x, df, ncp = 0, log = FALSE) { if (missing(ncp)) .Internal(dchisq(x, df, log)) else

Dear all I'm trying to run a cluster analysis with R Here are the commands: mydata <- na.omit(matrix) # listwise deletion of missing mydata <- scale(matrix) # standardize variables fit <- kmeans(mydata, 8) # 8 cluster solution # get cluster means aggregate(mydata,by=list(fit$cluster),FUN=mean) # append cluster assignment mydata <- data.frame(mydata, fit$cluster)

A colleague wrote the following syntax for me: D = read.csv("x.csv") ## Convert -999 to NA for (k in 1:dim(D)[2]) { I = which(D[,k]==-999) if (length(I) > 0) { D[I,k] = NA } } The dataset has many missing values. I am running several regressions on this dataset, and want to ensure every regression has the same subjects. Thus I want to drop subjects listwise for

Dear Rusers, I have met a difficult problem on explaining the differences of principal component analysis(PCA) between R,S-PLUS and SAS/STATA/SPSS, which wasn't met before. Althought they have got the same eigenvalues, their coeffiecients were different. First, I list my results from R,S-PLUS and SAS/STATA/SPSS, and then show the original dataset, hoping sb. to try and explain it.

Dear R users, I have a SAS codes with several loops in it, and i hope to use R to do the same task. The SAS codes are as follows, /*to generate the dataset*/ DATA Single_Simulation; DO se=0 to 1 by 0.01; DO sp=0 to 1 by 0.01; DO DR=0 to 1 by 0.01; TR=(DR+sp-1)/(se+sp-1+1.0e-12); Adjust_Factor=TR/(DR+1.0e-12); OUTPUT; END; END; END; RUN; /*to select some data*/ DATA

Dear Rusers, I want to know which function in R can perform the following tasks: 1.surface-data grid(x,y,z) #which could be done in splus, the name was from splus's options of graph 2. contourplot(x,y,z) #which could be done in splus By the way, where can i find some useful materials to learn to plot 3-dimensionel graphs?

Dear Rusers, I'd like to take the cases of cancer of the larynx in chorley(spatstat) to explain my question. I want to join the points of cancer of the larynx with the disused industrial incinerator to generate lines, and then calculate the angles of these line comparing the horizontal line? How can i get it? It seems to be difficult to get the angles Thanks a lot. -- With Kind

Hello, I don't know what's changed or how to figure out why as.roman() started to work different way lately on Mageia Cauldron. Cauldron is the latest development version of Mageia Linux.

Since applying the two patches you emailed me (one for cpu load, one for MS Excel issues): All is working fine now except MS Word; don't know if it's entirely related or a separate issue all together, but figured I'd post the details and see if you can think of anything; here's the behaior: Word (apparently) creates a "~384somerandomnamefile.tmp" when a user saves, the

Dear R users, We have some programs for the specific task in our research, but they were very commonly used. We want to make some functions for them, anybody can recommend any good tools to facilitate us to create R functions even without going deep into the theories of R functions ? Any suggestions or help are greatly appreciated. -- With Kind Regards, oooO::::::::: (..):::::::::
