[R] Writing a function, want a string argument to define the name of the excel sheet to be called

[Bryan Hanson]

Sure, change your example as follows and then you can pass the name properly:

foo <- function(x,y,NAME = "filename.csv"){

#make a matrix with x rows and y cols
M <- matrix(nrow=x,ncol=y)
#write the matrix
write.table(M, file = NAME,append=TRUE, sep = ",") 
}
