What is this error when I using Pipe in R

df2$Neighborhood %>% length()
df2$category %>% length()
table(df2$Neigborhood) %>% [order()]

This is the code I write to learn how to use the pipe. I'm not familiar with how to use it yet. An error occurred and I don't know how to fix it.

    [1] 481376
    [1] 481376
     Unknown or uninitialised column: 'Neigborhood'.integer(0)

The first two lines are able to generate a result. But not the third one. It means the neighborhood column is available. However, there are some mistakes in it. My purpose was to sort the table using function d2[order(d2)]. How can I fix it?

The issue is that there is 'h' missing in 'Neigborhood'. If we use the correct column name i.e. Neighborhood, it should work if we also specify the data i.e. . from the lhs of %>%

library(magrittr)
table(df2$Neighborhood) %>% 
      .[order(.)]

It may be also better to wrap with {} if there are multiple things involved

table(df2$Neighborhood) %>%
             {.[order(.)]}

Here the . represents the data from the lhs of %>%
