Grade Analysis R program . Can you please help me to solve this problem. Thanks in Advance

Question

You have a dataframe that includes grades of students.
Your program needs to take a number as input, and output the number of students who have a grade greater than the given input.
For example, for the input 89, the output should be:
[1] 3
as 3 students have grades greater than 89.

Answer 1

print(length(data$grade[data$grade > x ]))

Answer 2

This is only the code that it is already given.

Hint:
* subset the grade column so that you only keep keep the grade > x
* get the length of the remaining vector

Answer 3

print(length(t(subset(data, grade>x)["grade"])))

Answer 4

This is not your code. where is your attempts?

Answer 5

It's corrected now. It should work fine.

Answer 6

Hi, please link your code so we can help you!

Answer 7

input <- readLines('stdin')
x <- as.integer(input[1])

data <- data.frame(
"id" = c(1:10),
"grade" = c(75, 26, 54, 90, 86, 93, 48, 71, 66, 99)
)

Answer 8

SUNDAY Amos No, shouldn't work, R is case-sensitive

Answer 9

input <- readLines('stdin')
x <- as.integer(input[1])

data <- data.frame("id" = c(1:10),"grade" = c(75, 26, 54, 90, 86, 93, 48, 71, 66, 99))

print(length(t(subset(data,data$grade>x)["grade"])))

Answer 10

input <- readLines('stdin')
x <- as.integer(input[1])

data <- data.frame(
"id" = c(1:10),
"grade" = c(75, 26, 54, 90, 86, 93, 48, 71, 66, 99)
)
pet <- subset(data, grade>x)
Print(length(pet$grade))
#Should work fine.😉

Answer 11

@SUNDAY Amos

line 9, lower case P not capitol

Answer 12

input <- readLines('stdin')
x <- as.integer(input[1])

data <- data.frame("id" = c(1:10),"grade" = c(75, 26, 54, 90, 86, 93, 48, 71, 66, 99))

print(length(t(subset(data,data$grade>x)["grade"])))
