Merge two GADSdat objects into a single GADSdat object.

Source: R/merge.R
merge.GADSdat.Rd

Is a secure way to merge the data and the meta data of two GADSdat objects. Currently, only limited merging options are supported.

Usage

# S3 method for class 'GADSdat'
merge(
  x,
  y,
  by,
  all = TRUE,
  all.x = all,
  all.y = all,
  missingValue = NULL,
  missingValLabel = NULL,
  ...
)

Arguments

x

GADSdat object imported via eatGADS.

y

GADSdat object imported via eatGADS.

by

A character vector.

all

A character vector (either a full join or an inner join).

all.x

See merge.

all.y

See merge.

missingValue

A numeric value that is used to replace missing values introduced through the merge.

missingValLabel

The value label that is assigned to all variables into which missingValue is inserted.

...

Further arguments are currently not supported but have to be included for R CMD checks.

Value

Returns a GADSdat object.

Details

If there are duplicate variables (except the variables specified in the by argument), these variables are removed from y. The meta data is joined for the remaining variables via rbind.

The function supports automatically recoding missing values created through merging with a designated missing code (missingValue) and a value label (missingValLabel).
