`Hindex()` error: arguments imply differing number of rows

[jooyoungseo]

Hello,

I have downloaded the latest version of "bibliometrix" package from this GitHub repo. It seems like there is an error in Hindex() function. It fails even when example code is invoked. Please refer to the following reproducible code created by reprex package.
