umxSummarizeTwinData: 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")
)

Value

• formatted table, e.g. in markdown.

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.
