Creates a high dimensional dataset object. Only the required instances are loaded in memory to avoid unnecessary of resources and memory.
new()Method for initializing the object arguments during runtime.
HDDataset$new(
filepath,
header = TRUE,
sep = ",",
skip = 0,
normalize.names = FALSE,
ignore.columns = NULL
)filepathThe name of the file which the data are to be read from.
Each row of the table appears as one line of the file. If it does not
contain an _absolute_ path, the file name is _relative_ to the current
working directory, 'getwd()'.
headerA logical value indicating whether the file contains
the names of the variables as its first line. If missing, the value is
determined from the file format: 'header' is set to 'TRUE'
if and only if the first row contains one fewer field than the number of
columns.
sepThe field separator character. Values on each line of the file are separated by this character.
skipDefines the number of header lines should be skipped.
normalize.namesA logical value indicating whether the columns names should be automatically renamed to ensure R compatibility.
ignore.columnsSpecify the columns from the input file that should be ignored.
getColumnNames()Gets the name of the columns comprising the dataset
HDDataset$getColumnNames()A character vector with the name of each column.
getNcol()Obtains the number of columns present in the dataset.
HDDataset$getNcol()createSubset()Creates a blinded HDSubset for classification purposes.
HDDataset$createSubset(column.id = FALSE, chunk.size = 1e+05)
chunk.sizean integer value indicating the size of chunks taken over each iteration.
A HDSubset object.
