umxSummarizeTwinData: Summarize twin data

In tbates/umx: Structural Equation Modeling and Twin Modeling in R

Summarize twin data

Description

Produce a summary of wide-format twin data, showing the number of individuals, the mean and SD for each trait, and the correlation for each twin-type.

Set MZ and DZ to summarize the two-group case.

Usage

umxSummarizeTwinData(
  data = NULL,
  selVars = NULL,
  sep = "_T",
  zyg = "zygosity",
  age = "age",
  MZ = NULL,
  DZ = NULL,
  MZFF = "MZFF",
  DZFF = "DZFF",
  MZMM = "MZMM",
  DZMM = "DZMM",
  DZOS = "DZOS",
  digits = 2,
  report = c("markdown", "html")
)

Arguments

data	The twin data.
selVars	Collection of variables to report on, e.g. c("wt", "ht").
sep	The separator string that will turn a variable name into a twin variable name, default= "_T" for wt_T1 and wt_T2.
zyg	The zygosity column in the dataset (default "zygosity").
age	The age column in the dataset (default "age")
MZ	Set level in zyg corresponding to MZ for two group case (defaults to using 5-group case).
DZ	Set level in zyg corresponding to DZ for two group case (defaults to using 5-group case).
MZFF	The level of zyg corresponding to MZ FF pairs: default= "MZFF".
DZFF	The level of zyg corresponding to DZ FF pairs: default= "DZFF".
MZMM	The level of zyg corresponding to MZ MM pairs: default= "MZMM".
DZMM	The level of zyg corresponding to DZ MM pairs: default= "DZMM".
DZOS	The level of zyg corresponding to DZ OS pairs: default= "DZOS".
digits	Rounding precision of the report (default 2).
report	What to return (default = 'markdown'). Use 'html' to open a web table.

Value

• formatted table, e.g. in markdown.
