FUN
is applied to a
using additional arguments .FUNdots
to FUN
.
If a
is a list, the names of a
are applied to the output.
unaryapply_byname( FUN, a, .FUNdots = NULL, rowcoltypes = c("all", "transpose", "row", "col", "none") )
FUN | a unary function to be applied "by name" to |
---|---|
a | the argument to |
.FUNdots | a list of additional named arguments passed to |
rowcoltypes | a string that tells how to transfer row and column types of |
the result of applying FUN
"by name" to a
.
Note that .FUNdots
can be a rectangular two-dimensional list of arguments to FUN
.
If so, .FUNdots
is interpreted as follows:
The first dimension of .FUNdots
contains named arguments to FUN
.
The second dimension of .FUNdots
contains unique values of the named arguments
to be applied along the list that is a
.
The length of the first dimension of .FUNdots
is the number of arguments supplied to FUN
.
The length of the second dimension of .FUNdots
must be equal to the length of a
.
See prepare_.FUNdots()
for more details on the .FUNdots
argument.
Options for the rowcoltypes
argument are:
"all": transfer both row and column types of a
directly to output.
"transpose": rowtype of a
becomes coltype of output; coltype of a
becomes rowtype of output. "transpose" is helpful for FUN
s that transpose a
upon output.
"row": rowtype of a
becomes both rowtype and coltype of output.
"col": coltype of a
becomes both rowtype and coltype of output.
"none": rowtype and coltype not set by unaryapply_byname
. Rather, FUN
will set rowtype and coltype.
Note that rowcoltypes
should not be a vector or list of strings.
Rather, it should be a single string.
