umx_make_twin_data_nice
is a function to convert your twin data into a format used across umx
. Specifically:
Existing column for zygosity is renamed to "zygosity".
sep
is set to "_T"
The twinID is is set to sequential digits, i.e. 1,2...
umx_make_twin_data_nice(
data,
sep,
zygosity,
numbering,
labelNumericZygosity = FALSE,
levels = 1:5,
labels = c("MZFF", "MZMM", "DZFF", "DZMM", "DZOS")
)
a data.frame()
to check/convert.
existing separator string (will be updated to "_T").
existing zygosity column name (will be renamed zygosity
).
existing twin sequence string (will be updated to _T1, _T2, _T3).
If TRUE numeric zygosity levels will be set to labels.
legal levels of zygosity (ignored if labelNumericZygosity = FALSE (default 1:5)
labels for each zyg level c("MZFF", "MZMM", "DZFF", "DZMM", "DZOS").
