Map over multiple inputs simultaneously and return a vector of cognostics data frames

map2_cog(.x, .y, .f, ...)

pmap_cog(.l, .f, ...)

Arguments

.x, .y

Vectors of the same length. A vector of length 1 will be recycled.

.f

A function, formula, or atomic vector (see map2 for details)

...

additional arguments passed on to .f.

.l

A list of lists. The length of .l determines the number of arguments that .f will be called with. List names will be used if present.

Details

See map2
