I was working with Rstudio and Rmarkdown for some time now.
The data frames used to be displayed in this manner. I thought it is default for Rstudio.
Since I updated R from 3.4.4 to 3.5 the data frames are displayed in a manner similar to matrices. I'm working on Win10 device. I tried to change df_print setting in the document settings and it didn't work. I also tried creating different documents and reinstalling Rstudio and changing 'Show output inline for all Rmarkdown docuents' option in settings
It would be great if the data.frames looked as they used to.
