Checking p and maxval arguments

Checks the validity of the p and maxval input arguments that is used within the ctar package.

Usage

check_p(p, maxval, two_traits = FALSE)

Arguments

p

list of numeric vectors. Contains the p-values from each GWAS.

maxval

numeric scalar in range \((0, 1]\) (default: 1). The maximum value for p-values to be considered for analysis.

two_traits

logical (default: FALSE). Is the call for two traits?

Value

check_p returns a list with three elements:

• number_of_traits: The number of traits.

• number_of_snps: The number of SNPs.

• p_matrix: p as a matrix.
