R help - Jan 2011 - any similiar R fuction for matlab function 'fprintf'?

Dear All,

Currently, I am translating Matlab code to R. I met difficulties to translate
such Matlab codes into R:
fprintf(fid,(' SPLITTING RESULTS '));
fprintf(fid,(' \n'));
fprintf(fid,' Data base to analyze is a matrix %4i x %2i ',[n m]);
fprintf(fid,' \n');
fprintf(fid,' h is %2i',h);
fprintf(fid,' \n');
fprintf(fid,' group=0 outlier.\n');
fprintf(fid,' group=-1 discriminator or observation removed by the
rules.\n');
fprintf(fid,' \n');

Does anyone happen to know if R has similar function as fprintf in Matlab?

Thanks a lot!

Best
Zunqiu

Don't know any Matlab, but you should look at:

?cat
?sprintf
?format
?formatC

And in the future, why not provide an English description of what you  
are hoping for?

Also may want to consult:

There does not seem to be a function exactly similar to MATLAB's
"fprintf" in R, but you can achieve pretty much the same results using
something like the code below:

a <- 1:10
b <- 11:20
ab <- cbind(a,b)
sink("C:\\R\\test.txt")  # open file to write data to - file will be
deleted if it exists
cat(paste("The number is: ", 5, "\n", sep=""))
sprintf("The dimensions of matrix ab is: %i x %i", dim(ab)[1],
dim(ab)[2])                      # compare with the line below
cat(sprintf("The dimensions of matrix ab is: %i x %i", dim(ab)[1],
dim(ab)[2]),"\n")  # compare with the line above
cat(sprintf("%s is %f feet tall", "Sven",
7.1),"\n")
sink()                   # close file
# do more stuff
# append to previous file
sink("C:\\R\\test.txt", append=TRUE)  # open file for appending
cat("\n")
cat("Test in appending\n")
sink()                                # close file

There does not seem to be a function exactly similar to MATLAB’s “fprintf” in R,
but you can achieve pretty much the same results using something like the code
below:

a <- 1:10
b <- 11:20
ab <- cbind(a,b)
sink("C:\\R\\test.txt")  # open file to write data to - file will be
deleted if it exists
cat(paste("The number is: ", 5, "\n", sep=""))
sprintf("The dimensions of matrix ab is: %i x %i", dim(ab)[1],
dim(ab)[2])                      # compare with the line below
cat(sprintf("The dimensions of matrix ab is: %i x %i", dim(ab)[1],
dim(ab)[2]),"\n")  # compare with the line above
cat(sprintf("%s is %f feet tall", "Sven",
7.1),"\n")
sink()                   # close file
# do more stuff
# append to previous file
sink("C:\\R\\test.txt", append=TRUE)  # open file for appending
cat("\n")
cat("Test in appending\n")
sink()                                # close file
