Suffolk students can use R and R Studio by logging into their virtual desktop. More information here.
R Studio offers accounts on their cloud servers that let you use R and R Studio in the browser. The downside is that the free account only gives you 15 computing hours each month (a computing hour is charged when your account is active in-use). After that you pay for the marginal hour. For $5 a month you can get 50 computing hours. More details on the pricing plans are here.
In general we only recommend R Studio Cloud if you absotutely cannot install R/R Studio (or certain packages) on your computer, and you cannot use the Suffolk VDI.
