Auxiliary functions to (i) create a combination / C matrix with information on treatment combinations and interaction terms and (ii) a vector with all combinations in a component network meta-analysis.
createC(x, ...)# S3 method for matrix
createC(
x,
comb.ia,
inactive = NULL,
sep.comps = gs("sep.comps"),
sep.ia = gs("sep.ia"),
...
)
# S3 method for netcomb
createC(x, comb.ia = NULL, inactive = NULL, sep.ia = x$sep.ia, ...)
# S3 method for netmeta
createC(x, inactive = NULL, sep.comps = gs("sep.comps"), ...)
# S3 method for netconnection
createC(x, inactive = NULL, sep.comps = gs("sep.comps"), ...)
# S3 method for default
createC(x, n = 1, ...)
combinations(x, n = NULL)
R function createC returns a combination matrix / C matrix with
studies in rows and component and interaction terms in columns.
R function combinations returns a character vector with combinations.
A netcomb, netmeta or
netconnection object, a matrix or the number of components.
Additional arguments.
A character vector specifying treatment combinations which will be considered as interactions.
A character string defining the inactive treatment
component (see netcomb).
A single character to define separator between treatment components.
A single character to define separator for interactions.
A single number specifying the number of components in combinations.
