readsnpweights: Read Snp Weights/Loadings from a file

In danjlawson/pcapred: Produce PC Eigenvector Predictions From Plink Input Data And Loadings

Description

Read SNP weights from a variety of formats (plink/flashpca, either regular or transposed)

Usage

readsnpweights(
  snpweightsfile,
  mode = "flashpca",
  transpose = FALSE,
  colnames = NULL,
  verbose = TRUE
)

Arguments

snpweightsfile	The file to read
mode	either flashpca or plink; default "flashpca"
transpose	default FALSE, meaning treat columns as PCs and rows as SNPs. if TRUE, assume the laoding file is transposed from this.
colnames	(default NULL, meaning do no naming) names for the SNPs' comes from
verbose	(default TRuE) whether to show progress for file reading

Value
