pulver (version 0.1.1)

pulverize_all: pulverize_all

Description

Call pulverize for all combinations of input files.

Usage

pulverize_all(ys, xs, zs, output_file = NULL, colnames = c("y", "x", "z"),
  pvalue_threshold = 1, cores = 1L, overwrite = FALSE,
  suppress_return = TRUE)

Arguments

ys, xs, zs

lists of input file names (text or databel object file) containing tab-separated tables or matrices of type "double"

output_file

Output file name (default: NULL)

colnames

Column names of output file (default: "y", "x", and "z")

pvalue_threshold

p-value threshold (default: NULL, see pulverize)

cores

Number of cores (default: 1, see pulverize)

overwrite

If TRUE overwrite output_file (default: FALSE)

suppress_return

If TRUE return NULL instead of a data frame with p-values for the interaction term (default: TRUE)

Details

pulverize_all iterates through lists of file names or list of matrices and calls pulverize for each combination. Files must contain matrices with the same number of rows (= number of observations) and must have column names.

By default all results are written to output_file without returning a data frame (suppress_return = TRUE). Column names of the output file are by default set to "y", "x", and "z", but can be changed using the colnames argument. Furthermore, by default, output_file cannot be overwritten. For enabling overwrite of an existing output_file, set overwrite to TRUE.

z <- matrix(rnorm(nobs * 4), ncol = 4, dimnames = list(NULL,
paste0("column", 1:4)))
write.table(z, file = "z.txt", sep = "\t")

#run pulverize_all with generated files
