xprs_newcol

Purpose
Create and add a new empty column to a problem.
This function is similar to xprs_addcol but instead of returning the prob object, it returns the index of the newly created column.
Synopsis
xprs_newcol(prob, lb, ub, coltype = NULL, name = NULL, objcoef = NULL)
Arguments
prob 
The problem to which the column is to be added.
lb 
The lower bound for the new column.
ub 
The upper bound for the new column.
coltype 
Character specifying the column type. If this is NULL then the default Xpress column type is used (continuous). Possible values are:
C
indicates a continuous column.
B
indicates a binary column.
I
indicates an integer column.
S
indicates a semicontinuous column.
R
indicates a semiinteger column.
P
indicates a partial integer column.
name 
The name for the new column.
objcoef 
The objective coefficient for the new column.
Return value
The index of the newly created column.
Further information
This is a variant of addcols() that only adds a single column and also allows specifying type and name of the column.
