Pipe in R Studio

data("ToothGrowth")
View(ToothGrowth)

#Nested

arrange(filter(x,dose==0.5),len)
#Pipe

x <- ToothGrowth %>%
filter(dose==0.5) %>%
arrange(len)

When I use the Nested code its runs fine. ToothGrow data arrange and sort according to the code.
But when I add the pipe code. It gives the output in the console

x <- ToothGrowth %>%

  • filter(dose==0.5) %>%
  • arrange(len)

Why ?Please help me

They are equivalent.

The only difference in your code is that you've assigned the piped example but not assigned the nested one.

I also assume here...

... you'll be using "ToothGrowth" rather than "x"?

See the code below which demonstrates that these are equivalent:

library(tidyverse)

# Nested

nested <- arrange(filter(ToothGrowth, dose == 0.5), len)

# Pipe

piped <- ToothGrowth %>%
  filter(dose == 0.5) %>%
  arrange(len)

# Compare

nested == piped
#>        len supp dose
#>  [1,] TRUE TRUE TRUE
#>  [2,] TRUE TRUE TRUE
#>  [3,] TRUE TRUE TRUE
#>  [4,] TRUE TRUE TRUE
#>  [5,] TRUE TRUE TRUE
#>  [6,] TRUE TRUE TRUE
#>  [7,] TRUE TRUE TRUE
#>  [8,] TRUE TRUE TRUE
#>  [9,] TRUE TRUE TRUE
#> [10,] TRUE TRUE TRUE
#> [11,] TRUE TRUE TRUE
#> [12,] TRUE TRUE TRUE
#> [13,] TRUE TRUE TRUE
#> [14,] TRUE TRUE TRUE
#> [15,] TRUE TRUE TRUE
#> [16,] TRUE TRUE TRUE
#> [17,] TRUE TRUE TRUE
#> [18,] TRUE TRUE TRUE
#> [19,] TRUE TRUE TRUE
#> [20,] TRUE TRUE TRUE

#Pipe

x <- ToothGrowth %>%
filter(dose==0.5) %>%
arrange(len)

My this program is not working.

Output in the console is like this

x <- ToothGrowth %>%

  • filter(dose==0.5) %>%
  • arrange(len)

The normal result of running this code

x <- ToothGrowth %>%
  filter(dose==0.5) %>%
  arrange(len)

is that the console will show

> x <- ToothGrowth %>%
+   filter(dose==0.5) %>%
+   arrange(len)

If you want to see what x is, you can just type x in the console, like this

> x
    len supp dose
1   4.2   VC  0.5
2   5.2   VC  0.5
3   5.8   VC  0.5
4   6.4   VC  0.5
5   7.0   VC  0.5
6   7.3   VC  0.5
7   8.2   OJ  0.5
8   9.4   OJ  0.5
9   9.7   OJ  0.5
10  9.7   OJ  0.5
11 10.0   VC  0.5
12 10.0   OJ  0.5
13 11.2   VC  0.5
14 11.2   VC  0.5
15 11.5   VC  0.5
16 14.5   OJ  0.5
17 15.2   OJ  0.5
18 16.5   OJ  0.5
19 17.6   OJ  0.5
20 21.5   OJ  0.5

Check the Environment tab in RStudio to see if x is there.

Your code assigned the output to x as a new data frame, and it would not automatically print out the content in the console.
