Help me in R list

Question

str <- readLines('stdin')
x <- list("name"="James", "age"=42, "country"="USA")
a <- readLines('stdin')
x[["id"]] <-a
print(x)

Answer 1

Your code is reading your first input called str, which is not being assigned to your Named List.

This adjustment to your code will fix the problem, but I suspect you were attempting something more complex

#str <- readLines('stdin')
x <- list("name"="James", "age"=42, "country"="USA")
a <- readLines('stdin')
x[["id"]] <- a
print(x)

Answer 2

# Try inputting 2 lines of input
#Example:
# 123
# 456

# 456 will be assigned to x[["id"]]

str <- readLines('stdin')
x <- list("name"="James", "age"=42, "country"="USA")

x[["id"]] <- str[2]
print(x)

# From the R tutorial, 7.1

#R allows you to take user input and store them in a variable.

#The readLines function is used to read every line given as separate inputs, making it a convenient way to read multiple inputs.

#In order to access the inputs, we need to provide the number of the line we want to access using square brackets
