Create character vectors without quotation marks

When creating character vectors with several elements, it becomes a lot of quotes to type. cc provides a simple way to skip the quotes - but only for simple strings.

cc(...)

Arguments

...

The unquoted names that will become character values in the returned vector.

Value

A character vector

Details

Don't use cc with any special characters - only alphanumerics and no spaces supported. Also, remember that numerics are converted using as.character. Eg, this means that leading zeros are dropped.
