Hi all, I am Sahana. I am currently working on Libtheora for windows platform and very new to it. I am getting a lot of compiling errors. Since Libtheora depends on libogg and libvorbis i have added these as well to my workspace in VC++ 6. I have a doubt regarding the x86 and x86_vc folders described in the libtheora...

...I get the following errors : "NULL" (if printed without as.numeric), and "numeric(0)" if printed with the as.numeric. Again, if I use the same command without the loop, it gives the correct answer. Would be grateful for your inputs and ideas on this matter. Thanks in advance, Sahana.

Hi Sahana I must admit I'm not an expert in Theora. But the error message "Could not set keyframe interval to 64" might indicate that an attempt to set the keyframe frequency failed. Have a look at the keyframe_granule_shift attribute in the th_info struct. It says: The maximum distance betwe...

Hi, I'm trying to copy the first row of one data frame to another. This is the statement I am using : df2[1,]<-df1[1,]; I have printed them out separately: df1[1,] = A C D E F But after copying: df2[1,] = 96 29 88 122 68 Why isn't it copying? They are both data frames, and "as.character" isn't working either. Thanks for your input :) [[alternative HTML version

Hello :) I'm just starting out with R and would appreciate your help with a couple of problems I am running into. I have used Sys.glob to get a list of all filenames having a particular file extension (in my case, *.txt) I would now like to use this list in the following manner: I would like to use each filename from the list and open that file into a tab separated matrix and proceed. How can

Hi everyone, I'm using the following code to go over every element of a data frame (row wise). The problem I am facing is that the outer 'x' variable is not incrementing itself, thus, only one row of values is obtained, and the program does not proceed to the next row. This is the code: while(x<=coln) { while(y<=rown) { n<-as.numeric(df[[y]][x]);

HI, I'm looking for a function that does the same as deal() in MATLAB, i,e, for an array x[1 2 3] [a,b,c]=x; such that a=1, b=2, c=3 Does R have any functions similar to this? [[alternative HTML version deleted]]

Hi all, I am working on Libtheora. I have built the libtheora, libogg and libvorbis static libraries in vc++6. I'm testing the encoder for theora. I'm running tests on the encoder_example and i get the following errors in command prompt.

Hi, I am trying to create unique filenames for my output text file. The idea is that I would like to append a string to ".zsc.txt" so that all my files are uniquely named but with a similar format. I have tried adding the string variable to ".zsc.txt" while creating the output file name, i.e. write.table function, is what I have tried using : write.table(x,

Hi, I'm using R to do a series of calculation and I have gotten several warnings that say "NaNS produced". Whatever I could read on line gives me an idea that this warning is produced when the number is use is a negative log or otherwise mathematically problematic. I'm getting this error while using factorial() and gamma () on strictly positive numbers (always greater than zero).

Hi everyone, I am having trouble understanding where I went wrong with my code. It seems to logically be "all there" but the output says otherwise. I know this is a bit long but I can't seem to find the errors so I would appreciate your help :) This is my program : files<-Sys.glob("*.rescount.txt");length<-length(files);* #selecting all files of a particular

Any suggestions in this area would be greatly appreciate. I just recently found out at Sahana, and if there is anything else along those lines, I'd be very grateful.

Hi everyone, I'm trying to create unique filenames and then write a data frame into these files. This is the code I am using. str1<-"fname" str2<-".ext.txt"; FILENAME<-paste0(str1,str2); write.table(df, file=FILENAME,col.names=FALSE,row.names=FALSE,quote=FALSE,sep="\t"); Ideally, a file called fname.ext.txt should be created, containing the data

Hi, I am trying to create a data frame using the dimensions of another data frame that I have input. This is the code I am using: tab is the data frame that is input. c.leng<-length(tab[,1]); r.leng<-length(tab[1,]); opdf<-data.frame(ncol=c.leng, nrow=r.leng); a<-1; while(a<=c.leng) { opdf[[1]][a]<-tab[[1]][a]; a<-a+1; } This is the error message I am getting: Error in
