Usage
# S4 method for Spatial,data.frame
merge(x, y, by = intersect(names(x), names(y)),

 incomparables = NULL, duplicateGeoms = FALSE, ...)
Arguments
x

object deriving from Spatial

y

object of class data.frame, or any other class that can be coerced to a data.frame with as.data.frame

by, by.x, by.y

specifications of the common columns. See 'Details' in (base) merge.

all.x

logical; if TRUE, then the returned object will have all rows of x, even those that has no matching row in y. These rows will have NAs in those columns that are usually filled with values from y

suffixes

character(2) specifying the suffixes to be used for making non-by names() unique.

incomparables

values which cannot be matched. See match.

duplicateGeoms

logical; if TRUE geometries in x are duplicated if there are multiple matches between records in x and y
