filter_spatial function

Filter Spatial data

function to filter the spatial data slot of the mxFDA object.

filter_spatial(mxFDAobject, ..., based_on = "meta", force = FALSE)

Arguments

• mxFDAobject: object of class mxFDA
• ...: expressions that return a logical TRUE/FALSE value when evaluated on columns of the meta data slot. These expressions get passed to dplyr::filter() so must be compatible.
• based_on: character for which data slot to use for filtering, either 'meta', or 'spatial'. Default to 'meta'.
• force: logical whether or not to return empty spatial data if filtering results in 0 rows

Returns

object of class mxFDA with the spatial slot filtered. See make_mxfda() for more details on object

Examples

#load ovarian mxFDA object
data(ovarian_FDA)

#filter ages greater than 50
ovarian_FDA_age50 = filter_spatial(ovarian_FDA, age >= 50, based_on = 'meta')
