Error running Rstudio in my Laptop but the problem will be solved for a time being whenever I re-install the software. And after sometime it shows again. Kindly help me to resolve this issue. The problem is related to unused argument.

#Below is the example of the problem that I am facing

v<-c(1,2)
v

if I tried to run it, it will show:

Console:

Error in c(1,2), Unused argument c(2)
v
10+2i

It looks like your Renvironment don't understand you want to concatenate those 2 vectors.
I guess you used v<-c(1,2) - so could you please execute and paste the result of that in here:
sessionInfo()
