R programing inbuilt Titanic Data set

Question

I am new to R programming. I have to build titanic data in R. I want to find out how many child and adults are there in the dataset. Can someone give me hint to find the same?

I tried using length() function but it did not give the result.

Does this answer your question? https://stackoverflow.com/questions/27477232/how-can-i-count-the-number-of-instances-a-value-occurs-within-a-subgroup-in-r — vojtam, May 31 '21 at 06:21

Here's a solution in tidyverse syntax. It converts the Titanic dataset into a tibble (a type of dataframe), groups the data by the Age column, then uses n() to count the number of rows at each level of Age, giving the number of children and adults.

library(tidyverse)

Titanic %>% 
   as_tibble() %>% 
   group_by(Age) %>% 
   summarise(N = n())

This gives the output:

# A tibble: 2 x 2
  Age       N
  <chr> <int>
1 Adult    16
2 Child    16
