A collection of SNPEffectMatrix objects and their corresponding meta data

Slots

sems: A list of SNPEffectMatrix objects
semData: A data.table with meta data on each SEM
semKey: The name of a column in semData that matches the semIds in the sems list as a character. If column entries have a .sem suffix, a new column named SEM_KEY will be created without the .sem suffixes.

Examples

# build a SEM example matrix
m <- matrix(rnorm(16), nrow = 4)
colnames(m) <- c("A", "C", "G", "T")

# build a SNPEffectMatrix object
sm <- SNPEffectMatrix(sem = m, baseline = 1, semId = "sem_name")

# create a meta data table
md <- data.table::data.table(tf = "tf_name", sem = "sem_name")

# build a collection with 1 SEM
SNPEffectMatrixCollection(sems = list(sm), semData = md, semKey = "sem")
#> An object of class SNPEffectMatrixCollection
#> SEMs(1): sem_name
#> semData(2): tf, sem
