Usage

character; input SMILES.

verbose

logical; print messages during processing to console?

Note

This function can handle only one SMILES string.

Examples

if (FALSE) { # \dontrun{
# might fail if rcdk is not working properly
is.smiles('Clc(c(Cl)c(Cl)c1C(=O)O)c(Cl)c1Cl')
is.smiles('Clc(c(Cl)c(Cl)c1C(=O)O)c(Cl)c1ClJ')
} # }
