Descriptive Analysis in R Programming
In Descriptive statistics in R Programming Language, we describe our data with the help of various representative methods using charts, graphs, tables, excel files, etc. In the descriptive analysis, we describe our data in some manner and present it in a meaningful way so that it can be easily understood.
