|
file.to.read |
filename of file to be used as input. |
file.contains.header |
boolean. Does the file contain column names in its first row. |
file.contains.row.names |
boolean. Does the file contain row names in its first column. |
rows |
can be used to include or exclude rows during import. Only include a set of rows for import by supplying positive row numbers or ranges (eg. "1,2,3" or "1:3 will both limit the import to rows 1 to 3). Exclude a set of rows for import by supplying negative row numbers or ranges (eg. "-1,-2,-3" or "-1:-3 will both exclude rows 1 to 3 (and include the other rows)). |
cols |
can be used to include or exclude columns during import. Only include a set of columns for import by supplying positive row numbers or ranges (eg. "1,2,3" or "1:3 will both limit the import to columns 1 to 3). Exclude a set of columns for import by supplying negative columns numbers or ranges (eg. "-1,-2,-3" or "-1:-3 will both exclude columns 1 to 3 (and include the other columns)). |
separator |
which separator symbol is used in the file to separate the data values (eg. "\t" for tab separated values, or "," for comma separated values). |
force.numeric |
