Command Lines error in Rstudio console

by

In “An Introduction to R” manual (help.start()), Section 1.8:

Command lines entered at the console are limited to about 4095 bytes (not characters).

[footnote] Some of the consoles will not allow you to enter more, and amongst those which do some will silently discard the excess and some will use it as the start of the next line.

Based on the comments, there does indeed seem to be some variation across consoles in how this is handled. From the OP, we can conclude that RStudio does not allow you to enter more bytes. Currently, RStudio does not acknowledge or intend to address this.

I also found a 2006 conversation in the R devel mailing list where Brian D. Ripley explained the issue and the documentation above. It looks like the limit has changed since then (when it was 1024 bytes).

It’s worth noting that it works fine in a sourced script (even when “hard coded”). Only the REPL seems to be at fault.
