I have been using R, SAS and Stata since 2008. I'm a big fan of RStudio and R in particular except for the data viewer in Rstudio. It's 15+ times slower in scrolling horizontally or vertically as compared to SAS and Stata with the same data file making the concept of the data viewer in RStudio unusable. It's with all datasets. Right now I'm working on a small dataset of 2000 variables and about 140k obs and RStudio freezes for 10 seconds when i open the viewer by clicking on the dataset icon in the Environment. The viewer reacts to the horizontal scrolling bar clicks with about 2-3 seconds delay and it's impossible to drag the slider horizontally at all. I can post a recording of a comparison between the 3 using some public data.
It's been the case for all RStudio versions for all R versions for the last 6-7 years. Viewing and scrolling the same data in SAS with its "data on disk" and STATA with its "data in ram" is instantaneous. My system is AMD TR 1900x at 4ghz with 128gb of DDR4 2733 cas 14 ram.
Is there some setting I'm missing or is there a different package for viewing data in RStudio? Right now I have to save the data in either dta or sas7bdat for viewing.
