ez.2factor: ef->f, g/h->h, i=i, factor[x,y,z]<j/k

In jerryzhujian9/ezmisc: ez Zhu's miscellaneous functions

ef->f, g/h->h, i=i, factor[x,y,z]<j/k

Description

ef->f, g/h->h, i=i, factor[x,y,z]<j/k
number e->f[(0/1)]| attr number g(0/1)–>factor attr number h[0/1] |factor char i[girl/boy] |char j->k[(girl/boy)]

Usage

ez.2factor(
  x,
  col = NULL,
  add.non.labelled = TRUE,
  drop.na = FALSE,
  ref.lvl = NULL,
  ...
)

Arguments

x	a data frame or a vector/col
col	internally evaluated by eval('dplyr::select()') if x is a data frame, col is specified (e.g., "cond"), convert that col only if x is a data frame, col is unspecified (i.e., NULL default), convert all possible cols in x if x is not a data frame, col is ignored
add.non.labelled	Logical, if TRUE, non-labelled values also get value labels.
drop.na	Logical, if TRUE, all types of missing value codes are converted into NA before x is converted as factor. If FALSE, missing values will be left as their original codes. See 'Examples' and get_na.
ref.lvl	Numeric, specifies the reference level for the new factor. Use this parameter if a different factor level than the lowest value should be used as reference level. If NULL, lowest value will become the reference level. See ref_lvl for details.

Details

Variable label will be kept. wrapper of sjmisc_to_factor

Value

returns a factor with number as its levels or a data frame with changed col(s)
