- printf:
-
- Syntax: printf ( format_string , VARi ... )
-
- Description:
-
- The RLaB printf() is a limited feature version of the
- C-language printf(). The features are limited because RLaB
- does not support all of the data type the C-language does.
-
- format_string: must be a valid printf format string
-
- VARi: are any number of constants or variables that match the
- format string. printf() cannot print out vector, matrix, or
- list objects as a whole. Valid print objects are strings,
- constants, and scalars.
-
- The following shows how one might print out the annotated
- contents of a matrix.
-
- for(i in 0:size(a)[0]-1) {
- for(j in 0:size(a)[1]-1) {
- printf("a[%i;%i] = %f\n", i, j, a[i;j]);
- }
- }
-
- It would be more efficient to use:
-
- write("stdout", a);
-
- since write() knows how to deal with entire data objects.
-
- See also: fprintf, sprintf, write, read
