I have a general question. Is there a setting that can be used for a multiple line type? The situation is that I want a solid line between x and y points but if the y point is missing, I want a dashed line type to the next point. In other words, if point 1 to 2 exists, make that line solid, otherwise, make it dashed up to the next existing x/y point. Additionally, what plot type would you

Is there anyway to preset date formats? I have a date from a cover.dbf that is shown as this: > cover$FINALREPOR [1] "2003-06-24" The numeric value in cover$FINALREPOR is 12227. I'd rather not create another vector to hold the properly formatted date. When I put this in a WordPerfect merge, I want the date to be June 24, 2003. I could take care of the problem in a

In this simple function, how can I pass strings for index and column names to the function? I've posted this type of question before and received no response. Maybe this example will be easier to understand and troubleshoot. ds <- function(myds, vec) {myds[[vec]]*2} ds1 <- c(X=list(1:10), Y=list(11:20)) ds(get("ds1"),get("Y")) khobson at odot.org Kenneth Ray

How can I stop the following warning from occuring? invalid factor level, NAs generated in: "[<-.factor"(`*tmp*`, iseq, value = structure(1, .Label = "12", class = "factor")) The Label messages are for "5", "8", "12" and "46". I want the NAs to be generated as needed. Is this causing R to slow down by generating the warning

For windows, how can I list only the folders in some folder? I was thinking that dir() and file.info() with isdir==TRUE being something that might work. These folders or directories are numerically named with no dot extension names or other characters. Typically, these are 3132, 3334, ... Here is what I tried. The last line is where I need more work. pData="C:/Myfiles/R/Data/" setwd

Hi Kenneth: I tried: list.files(path="c:\\pctexv4\\samples") and that worked just fine. Hope this helps!

I am a new user of R so please bear with me. I have reviewed some R books, FAQs and such but the volume of material is great. I am in the process of porting my current SAS and SVS Script code to Lotus Approach, R and WordPerfect. My question is, can you help me determine the best R method to implement the Hoaglin Outlier Method? It is used in the Appendix A and B of the fo llowing link.

Please allow me an unusual question. Is there any way that R can be closely integrated with a Microsoft Powerpoint presentation? I would like to embed R calculations in Powerpoint so that I will start Powerpoint, be prompted to enter some parameters, and an R function will run and return values and graphs. Thanks, John R 2.1.1 windows 2k John Sorkin M.D., Ph.D. Chief, Biostatistics and

I use R to generate data and I need to estimate the data by egarch (that doesn't have in R). So how I can call egarch from SAS in R. Regards, luck

A<-c(1,2,NA,7,5) B<-c(3,4,1,4,1) C<-c(6,5,6,NA,9) D<-c(8,7,4,6,2) df1<-cbind(A,B,C,D) for(i in seq(1,ncol(df1)-1, by=2)) { ifelse(df1[,i]=="NA",df1[,i+1]=="NA",df1[,] ) } Tried several variations but none worked. I wish to find any NA's in column's 1 or 3 and change the numerical value to the right of the " NA"'s . In this case I

I write a function to get the frequency and prop of a variable. freq<-function(x,digits=3) {naa<-is.na(x) nas<-sum(naa) if (any(naa)) x<-x[!naa] n<-length(x) ta<-table(x) prop<-prop.table(ta)*100 res<-rbind(ta,prop) rownames(res)<-c("Freq","Prop") cat("Missing value(s) are",nas,".\n") cat("Valid case(s)

I'm new to R and not an experienced writer of programs, which may help explain my question. I wish to create a table or data frame which contains the quantiles of the columns in the data frame DF. I wish to produce a table T where T[1] shows me the quantiles of column DF[1] right up through the entirety of DF. Tried several approaches with limited success. This looked like the best

Question : Is it possible to create a function, using a for ifelse function, inside sapply, to compare the values in one data frame to a set of upper and lower limits in another data frame, same number of columns., Take the values which meet the requirements "TRUE" and create a new data frame or table containing the filtered data? Can you give me a shove in the correct direction?

hi, i am using the RODBC package to read excel files using odbcConnectExcel and susequently sqlFetch to read the contents of the file. the file that i use is just a matrix of numbers thats all. no headers and column names. what happens is that the sqlFetch is not reading my first row of numbers. i have tried different combinations of colnames and rownames logical values but that first row is not

Dear R People: I would like to generate a vector/variable name from within a loop to be passed to a table function. This is what I have so far: >assign("p1",paste("raw3.df$",rw2$V1[3],sep="")) >p1 [1] "raw3.df$CITIZEN" > Essentially, I want to use the raw3.df$CITIZEN along with another value to generate a table. However, I'm stuck here. I

Hi, I'm new to R. I'm using the R Gui and have tried to install additional packeges. When I choose Packages/Install package(s) I get the following error... utils:::menuInstallPkgs() Warning: unable to access index for repository http://cran.ma.imperial.ac.uk/bin/windows/contrib/2.15 Warning: unable to access index for repository http://www.stats.ox.ac.uk/pub/RWin/bin/windows/contrib/2.15

This is a best practices / style question. The way I use RODBC is I something like this: > foo <- sqlQuery(db, "select * from foo") > apply(foo, 1, function{...}) That is, I use apply to iterate over each result -- row -- in the RODBC-produced dataframe. Is this how one generally wants to do this? My concern is that when apply iterates over the rows, it uses as.matrix()

Is there available in R a generalized inner product or matrix product, similar to 'outer(x,y, fun)', where one can specifiy an arbitrary function in place of ordinary multiplication? Here's my application. I frequently analyze user questionnaires from our HR/training department. These have questions of the form "please rate your skill in task X", and other questions

Ahhh this could be my problem! I just checked which wires on the RJ11 cable had a voltage across them and it was the yellow and green (3 & 4?). From what someone posted the other day it's supposed to be Bumble Bee and Christmas Tree. I did have to get a technician out to fix my line when it was first installed because it was dead. Maybe he wired it up incorrectly or maybe they just do it
