miscGlobal(data, siglev = 1e-10, subt.mean = FALSE, PCnum = NULL,
  maxPCnum = 20, eps = NULL, rm.PCdir = TRUE, ADcutoff = 10,
  filter.dir = TRUE, less.return = TRUE)

Arguments

data

precessed RNA-seq data from process_data

siglev

the significance level of the Chi-squared distribution. Default is 1e-10.

subt.mean

logical, whether to subtract mean before SVD. Default is FALSE.

PCnum

the number of PCs to be used. If NULL (the default) the number of PCs will be estimated.

maxPCnum

the maximum number of PCs to be used. Default is 20.

eps

tuning parameter for estimating the number of PCs. If NULL (default), eps = (1/nrow(data))

rm.PCdir

logical or numeric, the indices of PCs to be excluded from further study. If TRUE (the default), this automatically excludes a set of PCs that deviate from normality. If a sequence is specified, the corresponding PCs will be excluded.

ADcutoff

a cutoff value for checking the normality based on Anderson-Darling test statistic

filter.dir

logical, wether to filter out directions that deviate from normality. Default is TRUE.

less.return

logical, whether to show less results and not to return large matrices. Default is TRUE.
