我们可以用<代码>desc加以总结,以便从一开始就获得缺失的数值。

flights %>% 
    arrange(desc(is.na(dep_time)),
           desc(is.na(dep_delay)),
           desc(is.na(arr_time)), 
           desc(is.na(arr_delay)),
           desc(is.na(tailnum)),
           desc(is.na(air_time)))

只有在根据这些变量得出的变量中才发现了NA值。

names(flights)[colSums(is.na(flights)) >0]
#[1] "dep_time"  "dep_delay" "arr_time"  "arr_delay" "tailnum"   "air_time" 

Instead of passing each variable name at a time, we can also use NSE arrange_

nm1 <- paste0("desc(is.na(", names(flights)[colSums(is.na(flights)) >0], "))")

r1 <- flights %>%
        arrange_(.dots = nm1) 

r1 %>%
   head()
#year month   day dep_time sched_dep_time dep_delay arr_time sched_arr_time arr_delay carrier flight tailnum

Update

With the newer versions of tidyverse (dplyr_0.7.3, rlang_0.1.2) , we can also make use of arrange_at, arrange_all, arrange_if

nm1 <- names(flights)[colSums(is.na(flights)) >0]
r2 <- flights %>% 
          arrange_at(vars(nm1), funs(desc(is.na(.))))

或使用<条码>

f <- rlang::as_function(~ any(is.na(.)))
r3 <- flights %>% 
          arrange_if(f, funs(desc(is.na(.))))


identical(r1, r2)
#[1] TRUE

identical(r1, r3)
#[1] TRUE

他刚才告诉你:

arrange(flights, desc(is.na(dep_time)))

其他冰 sh或t:

arrange(flights, !is.na(dep_time))

或

arrange(flights, -is.na(dep_time))

以下各行各行各行各通:<代码>。 NA:

flights %>% 
    arrange(desc(rowSums(is.na(.))))

@akrun的解决方案是罚款。 然而,arrange_ is deprecated SE texts of main verbs. 为避免这种情况,我们可以使用<代码>eval。

nmf <- names(flights)[colSums(is.na(flights)) > 0]
rules = paste0("!is.na(", nmf, ")")
rc <- paste(rules, collapse = ",")
arce <-  paste("arrange(flights," , rc , ")")
expr <- parse(text = arce)
ret <- eval(expr)

Using the data frame (x) the code should be

arrange(df, !is.na(x))
