Answer 1

Extracting data from the dataframe in R language is easy. We have to make use of default methods in a better way.

#Returns third row with all columns
stocks[3,]

#Fourth and fifth row of ibm column
stocks[4:5, "ibm"]

#apple and micr columns using c() inside the brackets.

stocks[, c("apple","micr")]
