hello, thank you for the reply. That textbook is very useful, thanks for sharing. I installed both "tinyverse" and "dplyr" , and tried using the filter command and it was still unable to return anything for me.
I know this step is not difficult and I'm much more proficient in R than this, but it's stumping me 
here's the code I've tried so far:
filter(MIDB.4.3, V4 = 750)
Error in filter(MIDB.4.3, V4 = 750) : unused argument (V4 = 750)
filter(MIDB.4.3, ccode = 750)
Error in filter(MIDB.4.3, ccode = 750) : unused argument (ccode = 750)
filter(MIDB.4.3, ccode == 750)
Error in filter(MIDB.4.3, ccode == 750) : object 'ccode' not found
filter(MIDB.4.3, V4 == 750)
Error in filter(MIDB.4.3, V4 == 750) : object 'V4' not found
india <- filter(MIDB.4.3, V4 == 750)
Error in filter(MIDB.4.3, V4 == 750) : object 'V4' not found
