int2bits	Convert a bits object to an integer and vice versa
plot.qr_code	Plot the QR code
polynomialGenerator	Function to generate polynomial
print.bits	Print a bits vector Display the logical vector as a bit string where 'FALSE' is shown as '0' and 'TRUE' as '1'.
print.qr_code	Print the qr_code object
qrcode_gen	QRcode generator
qrFillUpMatrix	Function to fill up the data bits
qrInitMatrix	Function to initialize QRcode in matrix for different version
qrInterleave	Function to interleave the Data Code and Error Correction Core
qrMask	Apply mask to the QRcode matrix
qrVersionInfo	Function to identify the version of the QRcode based on input string
qr_code	Generate the QR code
qr_encode	Create the bit encoding
qr_error	Create the message and error code bit string
qr_matrix	Prepare matrices with default patterns and unmasked data A list with a matrix containing the default patterns (finder pattern, timing pattern, separators, alignment pattern and dark module), the unmask data pattern and the version.
qr_mode	Determine the required mode
qr_version	Determine the required version Returns a list with the version, error correction level and mode. The bit string encodes mode and the length of the input string.
versionPolyGen	Function to calculate and generate version polynomial
