I am running v1.0.44 (the company only upgrades periodically), so please ignore if this is possible in a later version.
A view tab (called by View()) can be useful for a quick look at the data, but is not very useful for any more detailed inspection. For such cases I copy the data to Excel. I realise that Excel screws up dates and other formats, but for rapid browsing, filtering, etc. it can be very useful.
Copying the data to the clipboard (before pasting to Excel) involves the somewhat tedious task of wrapping this expression around the data frame in the console:
write.table(df, "clipboard", sep = "\t", row.names = FALSE)
For large data frames this throws an error and e.g. "clipboard-10000", etc. must be used.
Would it be possible to add an option/button to the View() tab to copy the contents to the clipboard?
