R-help, I have a function which is exporting the output to a file via write.table(df, file = "file name.xls" ) What I want is to paste the file name (above) by taking the argument to the function as a file name something like this: MY.function<- function(df) { ... ... write.table(df,"argument.xls") } MY.function(argument) Thank you

[R] paste argument of a function as a file name
my.write <- function( obj, name ){ filename <- file=paste( name, ".txt", sep="") write.table( obj, file=filename, sep="\t", quote=F) } my.write( df, "output" ) Regards, Adai On Thu, 2005-11-10 at 13:28 +0000, Luis Ridao Cruz wrote:> R-help, > > I have a function which is exporting the output to a file via > write.table(df, file = "file name.xls" ) > > What I want is to paste the file name (above) by taking the argument to > the function as a file name > > something like this: > > MY.function<- function(df) > { > ... > ... > write.table(df,"argument.xls") > } > MY.function(argument) > > > Thank you > > ______________________________________________ > R-help at stat.math.ethz.ch mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html >

[R] paste argument of a function as a file name
Why not use something like MY.function <- function(x){ filn <- deparse(substitute(x)) filename <- paste(filn,"xls",sep=".") ... ... write.table(x,file=filename) } Med venlig hilsen Frede Aakmann T??gersen> -----Oprindelig meddelelse----- > Fra: r-help-bounces at stat.math.ethz.ch > [mailto:r-help-bounces at stat.math.ethz.ch] P?? vegne af Luis Ridao Cruz > Sendt: 10. november 2005 14:28 > Til: r-help at stat.math.ethz.ch > Emne: [R] paste argument of a function as a file name > > R-help, > > I have a function which is exporting the output to a file via > write.table(df, file = "file name.xls" ) > > What I want is to paste the file name (above) by taking the > argument to the function as a file name > > something like this: > > MY.function<- function(df) > { > ... > ... > write.table(df,"argument.xls") > } > MY.function(argument) > > > Thank you > > ______________________________________________ > R-help at stat.math.ethz.ch mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide! > http://www.R-project.org/posting-guide.html > >
