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

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

I am using rbind to add one list with one row to another master list. The problem is that not all columns exist in both lists. What methods would you recommend to reorder one list based on the column names of another? If both sets have the same order and columns, I can then use rbind. I can live with columns being added to the master list set it makes the task easier using something like

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.

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

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

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 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.

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

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

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?

Hello I think, I somewhat destroyed my btrfs filesystem on my Ubuntu 13.04 kernel 3.8.0-25-lowlatency system. It got destroyed, because the system was hanging for some other reason and I had to remove power... When I try to mount my filesystem (there''s only one, with a few subfilesystems), the system crashes. Also btrfsck dies; always like this: a@ask-home:~$ sudo

I have what is likely to be a simple question about the else keyword. The usage in the help pages is as follows: if(cond) cons.expr else alt.expr I would expect to be able to use it in the following way as well: if(cond){ cons.expr } else alt.expr This results a syntax error. Am I doing something wrong, or doesn't R support the spanning of the combination of if and else

Hello, I urgently need a histogram of the vector geo1$ds1 but: > hist(geo1$ds1) Error in hist(geo1$ds1) : unused argument(s) ( ...) I can use density, summary, boxplot and stem with this vector but not hist ? Any suggestions ?

I have a set of data frames ds1, ds2, ... each having the same columns and column names: ds1 <- data.frame(x=c(1,2,3,4), y=c(5,6,7,8)) ds1 <- data.frame(x=c(9,10,11,12), y=c(13,14,15,16)) ... and I would like to combine them into just one data frame like ds <- rbind(ds1, ds2, ...) Because there are so many of them, I will have to use a character array nms <-

Using R version 2.4.1 (2006-12-18) on Windows, I have a dataset which resembles this: id att1 att2 att3 1 1 1 0 2 1 0 0 3 0 1 1 4 1 1 1 ratings <- data.frame(id = c(1,2,3,4), att1 = c(1,1,0,1), att2 = c(1,0,0,1), att3 = c(0,1,1,1)) I would like to get a cross tab of counts of co-ocurrence, which might resemble this:

Hello R users, When trying to fit a nonlinear mixed model to a respiration time series, I get the following error message: Error in recalc.varFunc(object[[i]], conLin) : dims [product 30] do not match the length of object [34] In addition: Warning message: In conLin$Xy * varWeights(object) : longer object length is not a multiple of shorter object length Below is an example that generates
