Rset |
Purpose
Synopsis
procedure Rset(dst:string, value:[set|array|list of] boolean|integer|real|string)
Arguments
|
dst
|
An R variable name
|
|
value
|
The Mosel value to be assigned to
dst
|
Example
The following example assigns values 1.2, "hello" and an array with numbers 1 to 6 to the R objects
a_num,
a_string and
a_vec respectively:
Rset('a_num', 1.2)
Rset('a_string', 'hello')
Rset("a_vec", 1..6) ! An R vector with real values 1 to 6
Rset("dim(a_vec)", [2,3]) ! Change its dimensions into a 2x3 matrix
Further information
1. A new temporary R entity is created from
value and then assigned to
dst, unless
value is a scalar and
dst is an existing R entity of the corresponding type, in which case
dst is just set to the new value
2. Argument
dst can represent any assignable expression (including subsetting and attributes).
3. The type of argument
value can be any elementary Mosel type, or an array, list or set of these (compositions are not supported).
4. When
value is an array, for each of the array's dimensions, its index values are exported into the corresponding R array's
names or
dimnames attribute (after conversion to string) unless the indices are integer values from 1 to that dimension size.
5. If
value is a dynamic array, only the existing values are copied to R and the remaining array entries are set to NA (Not Available).
