Data/ data frame

[eostrinidad]

I get this message whenever I use PanelMatch:

please convert data to data.frame class
In addition: Warning message:
In if (class(data) != "data.frame") stop("please convert data to data.frame class") :
the condition has length > 1 and only the first element will be used

However, my data is already a data frame. Any advice for this? Thanks!

Hi @eostrinidad , thanks for using the package!

It is a bit hard to say, but have you tried explicitly setting the class of the data -- something like class(data) <- "data.frame"? This error seems to suggest that the data object being passed has more than one class associated with it.

Thanks so much, Adam! This was really very helpful and I can't wait to use the program.
