as.tableColumns

Usage

as.tableColumns(source, doFullFileScan=TRUE, ... )

Arguments

source
A data frame or path to a csv file
doFullFileScan
Should the services suggest column types based on the entire file (TRUE - default) or the first 1000 rows of the file (FALSE). For large homogeneous files, doFullFileScan=FALSE will be faster, but may miss-classify the column types.
linesToSkip
When 'source' is a file path: The number of lines to skip from the start of the file. The default value of 0 will be used if this is not provided by the caller.
quoteCharacter
When 'source' is a file path: The character to used for quoted elements in the provided file. The default character '"' will be used if this is not provided by the caller.
escapeCharacter
When 'source' is a file path: The escape character used for escaping a separator or quote. The default character '\' will be used if this is not provided by the caller.
lineEnd
When 'source' is a file path: The line feed terminator to be used for the resulting file. The default value of '\n' will be used if this is not provided by the caller.
separator
When 'source' is a file path: The delimiter to used for separating entries in the provided file. The default character ',' will be used if this is not provided by the caller. For tab-separated values use '\t'
