Error: object not found after being defined in R

Question

I have just started using R, and I seem to be falling over at the first hurdle...

I have defined an object in my R project which is the csv data for a file I have stored on my PC:

rgvaAssessment<-read.csv("C:\\Users\\cheddar\\Downloads\\attachments\\rgva_assessment X.csv")

However, when I type the object name in the R console, I get the following error:

> rgvaAssessment
Error: object 'rgvaAssessment' not found

Could someone please let me know what obvious error I am making here? The file definitely exists in the defined location.

Thanks
