\title{An R6 class for chemical entities with associated data}
\format{
An \code{\link{R6Class}} generator object
}
\description{
The class is initialised with an identifier. Chemical information is retrieved from
the internet. Additionally, it can be generated using RDKit if RDKit and its
python bindings are installed.
}
\examples{
oct <- chent$new("1-octanol", smiles = "CCCCCCCCO")
print(oct)
if (!is.null(oct$Picture)) {
  plot(oct)
}

caffeine <- chent$new("caffeine")
print(caffeine)
if (!is.null(caffeine$Picture)) {
  plot(caffeine)
}
