R中循环中的变量编码

Question

我想一起重新编码几个变量。所有这些变量将经历相同的重新编码更改。为此，我遵循了以下主题。下面的线程描述了两种方法。1）。使用列号2）。使用变量名

我都尝试过，但收到错误消息。

[错误消息1）和2）。错误（函数（var，重新编码，as.factor，as.numeric = TRUE，级别）：未使用的参数（2 =“ 1”，3 =“ 1”，1 =“ 0”，4 =“ 0”，na.rm = TRUE）

recode variable in loop R

#Uploading libraries
library(dplyr)
library(magrittr)
library(plyr)
library(readxl)
library(tidyverse)

#Importing file
mydata <- read_excel("CCorr_Data.xlsx")
df <- data.frame(mydata)
attach(df)

#replacing codes for variables
df %>%
  mutate_at(c(1:7), recode, '2'='1', '3'='1', '1'='0', '4'='0', na.rm = TRUE) %>%
  mutate_at(c(15:24), recode, '2'='0', na.rm = TRUE)


df %>% 
  mutate_at(vars(E301, E302, E303), recode,'2'='1', '3'='1', '1'='0', '4'='0', na.rm = TRUE) %>%
  mutate_at(vars(B201, B202, B203), recode, '2'='0', na.rm = TRUE)

有人可以告诉我我要去哪里错吗？

我的数据集中缺少值，这就是为什么我包含na.rm = T的原因。我什至尝试不包含缺少值的命令，即使这样，错误消息也相同。

请参见下面的示例数据。

structure(list(Country = c(1, 1, 1, 1, 1, 1), HHID = c("12ae5148e245079f-122042", 
"12ae5148e245079f-123032", "12ae5148e245079f-123027", "12ae5148e245079f-123028", 
"12ae5148e245079f-N123001", "12ae5148e245079f-123041"), HHCode = c("122042", 
"123032", "123027", "123028", "N123001", "123041"), A103 = c(2, 
2, 2, 2, 2, 2), A104 = c("22", "23", "23", "23", "23", "23"), 
    Community = c("Mehmada", "Dhobgama", "Dhobgama", "Dhobgama", 
    "Dhobgama", "Dhobgama"), E301 = c(3, 3, 3, 3, 3, 3), E302 = c(3, 
    2, 4, 4, 3, 3), E303 = c(3, 2, 3, 3, 3, 3), E304 = c(3, 4, 
    4, 4, 3, 3), E305 = c(3, 2, 3, 3, 3, 3), E306 = c(3, 3, 3, 
    3, 3, 3), E307 = c(3, 3, 3, 3, 3, 3), E308 = c(3, 1, 3, 3, 
    3, 3), B201.1 = c(NA, 1, 1, 1, 1, 1), B202.1 = c(NA, 1, 1, 
    1, 1, 1), B203.1 = c(NA, 1, 1, 2, 2, 1), B204.1 = c(NA, 2, 
    1, 2, 1, 1), B205.1 = c(NA, 2, 1, 2, 2, 2), B206.1 = c(NA, 
    1, 1, 1, 2, 1), B207.1 = c(NA, 2, 1, 2, 2, 1), B208.1 = c(NA, 
    2, 2, 2, 2, 2), B209.1 = c(NA, 2, 1, 1, 1, 1), B210.1 = c(NA, 
    1, 1, 1, 1, 1)), row.names = c(NA, 6L), class = "data.frame")
    ```

Answer 1

尝试使用：

library(dplyr)

df %>%
  mutate_at(1:7, recode, '2'='1', '3'='1', '1'='0', '4'='0') %>%
  mutate_at(15:24, recode, '2'='0')

Answer 2

问题出在na.rm = TRUE中，recode没有该参数

library(dplyr)   
df %>% 
  mutate_at(vars(E301, E302, E303), recode,'2'='1', '3'='1', '1'='0', '4'='0') %>%
  mutate_at(vars(B201, B202, B203), recode, '2'='0')
