[R] continuation lines in R script files

When I have to enter a very large matrix into the R console, I can make use of the continuation feature in the console to enter the matrix in pieces (e.g., on a row by row basis). So, for example, the console would show the "+" sign for continuation lines - something like what I've written below:


+  0.05,0,0,
+ 0,0.1,0),
+ 3,3,byrow=T)

(obviously, for a matrix this small - 3x3 - I could enter it all on a
single line, this is just to demonstrate)

My question is - how do you accomplish the same thing in an R script file? I've tried literally copying the preceding - syntax error at the second line. I've also tried


Again, syntax error, at the second line...

After multiple searches for 'continuation line', with no luck
(everything I found refers to the R console, no a script file), I'll ask
here. Basically, I want to know how to get an R script to handle a structure entered over multiple lines (e.g., a matrix). This is default behaviour in .m files in Matlab, and most other environments I've ever worked in (e.g., SAS looks for the ; to indicate end of a line).

Thanks in advance...
