Description

Computing the Cronbach alphas for multiple factors.

Usage

cronbach_alpha(
  ...,
  data,
  var_name,
  group = NULL,
  quite = FALSE,
  return_result = FALSE
)

Value

a data.frame object if return_result is TRUE

Arguments

...

Items. Group each latent factors using c() with when computing Cronbach alpha for 2+ factors (see example below)

data

data.frame. Must specify

var_name

character or a vector of characters. The order of var_name must be same as the order of the ...

group

optional character. Specify this argument for computing Cronbach alpha for group separetely

quite

suppress printing output

return_result

If it is set to TRUE, it will return a dataframe object

Examples

cronbach_alpha(
  data = lavaan::HolzingerSwineford1939,
  var_name = c('Visual','Textual','Speed'),
  c(x1,x2,x3), # one way to pass the items of a factor is by wrapping it with c()
  x4:x6, # another way to pass the items is use tidyselect syntax 
  x7:x9)
