Here we are explaining how to write an R program to drop row(s) by number from a given data frame. Here we are using a built-in function data.frame(). A data frame is used for storing data tables which has a list of vectors with equal length. The data frames are created by function data.frame(), which has tightly coupled collections of variables.. The syntax of this function is,
– where dots(…) indicates the arguments are of either the form value or tag = value and row. name is a NULL or a single integer or character string.
Below are the steps used in the R program to drop row(s) by number from a given data frame. In this R program, we directly give the data frame to a built-in function. Here we are using variables E, N, S, A, Q for holding different types of vectors. Call the function data.frame() for creating dataframe. Finally, drop row(s) by number from a given data frame by calling like E <- E[-c(2, 4, 5), ]
E = data.frame( N = c('Jhon', 'Hialy', 'Albert', 'James', 'Delma'), S = c(10, 9.5, 12.2, 11, 8), A = c(2, 1, 2, 4, 1), Q = c('yes', 'no', 'yes', 'no', 'no') ) print("Original dataframe:")
##  "Original dataframe:"
## N S A Q ## 1 Jhon 10.0 2 yes ## 2 Hialy 9.5 1 no ## 3 Albert 12.2 2 yes ## 4 James 11.0 4 no ## 5 Delma 8.0 1 no
E <- E[-c(2, 4, 5), ] print("Final dataframe:")
##  "Final dataframe:"
## N S A Q ## 1 Jhon 10.0 2 yes ## 3 Albert 12.2 2 yes
