I want to install the 'fitdistrplus' package into rstudio, I got the following Error message

Error in install.packages : object 'fitdistrplus' not found

Please, help

The name of the package has to be quoted, otherwise R thinks you are referring to an object that doesn't exist.

install.packages("fitdistrplus")

Thank you very much for your reply. I guess I omitted the quotation. I have installed it
