Thank you very much Mr andresrcs for the info I have installed install.packages("bibliometrix", dependencies = T). However, I got this update in Console after installation:
package ‘farver’ successfully unpacked and MD5 sums checked
Error in install.packages : ERROR: failed to lock directory ‘C:\Users\LEN0V0\Documents\R\win-library\3.6’ for modifying
Try removing ‘C:\Users\LEN0V0\Documents\R\win-library\3.6/00LOCK’
#Load bibliometrix
library('bibliometrix')
Error in library("bibliometrix") :
there is no package called ‘bibliometrix’
