field.exists

field

data

Checks whether a field exists in a dataset.

Uses Protovis to provide web graphics for R (exposes most
low-level functions).  Package is still under active
development and shouldn't be considered stable until version
0.1.  Currently uses a web browser to process JavaScript,
although future version will process JavaScript directly and
return the SVG output.  Also does not properly support discrete
labels (e.g. with histograms) or statistical functions.  See
website for more details.
