umx_scale_wide_twin_data: Scale wide twin data

Description

Scale wide data across all twins. You offer up a list of variables to scale, e.g. c("DEP", "bmi") and the separator (e.g. sep = "_T") and twin suffixes e.g. 1:2 that paste together to make complete variable names: e.g. "DEP_T1" and "DEP_T2".

Usage

umx_scale_wide_twin_data(varsToScale, sep, data, twins = 1:2)

Arguments

varsToScale

The base names of the variables ("weight" etc.)

sep

The suffix that distinguishes each case, e.g. "_T")

data

A wide dataframe

twins

Legal digits following sep (default 1:2)

Value

• dataframe with varsToScale standardized
