Installing R & R Studio

[datafan]

I installed R and R Studio so I can use some of the "Box & Wiskers" & "Outliers" visuals.

After adding some of the visuals and attempting to use them.. I get an error saying:

-------------------------------

Can't display this visual

R script error.

Loading required package: XML

Loading required package: htmlwidgets

Loading required package: ggplot2

Loading required package: plotly

.....

Error in ggplot() : could not find function "ggplot"

Execution halted.

-------------------------------

Can someone shed some light on this or provide a solution to this?

Much appreciate the response!!

Thanks in advance.
