Question

我对R很陌生，请耐心等待。在这种情况下，数据并不重要。错误和导致错误的代码如下。我在下面的代码的最后一部分中安装和加载软件包。我的问题是，安装并加载下面列出的软件包是否会导致此错误。我以前用较短的软件包阵容成功地执行了此操作，但是此后丢失了该代码，现在遇到了重命名错误。是否有任何想法是否可以互相抵消？

 current %>%
 filter(AreaType=="State" & Ownership=="Private" & Industry=="10 Total, 
 all industries")->current
 last %>%
 filter(AreaType=="State" & Ownership=="Private" & Industry=="10 Total, 
 all industries")->last


 keepsc <- 
c("St","Year","JulyEmployment","AugustEmployment","SeptemberEmployment")
 current<- current[keepsc]

 keepsl <- 
 c("St","JulyEmployment","AugustEmployment","SeptemberEmployment")
 last<- last[keepsl]

 current<- rename(current,

 Error in rename(last, JulyEmployment17 = JulyEmployment, 
 AugustEmployment17 = AugustEmployment,  : 
 unused arguments (JulyEmployment17 = JulyEmployment, AugustEmployment17 
 = 
 AugustEmployment, SeptemberEmployment17 = SeptemberEmployment)


 #load packages
 x = c("tidyverse", "rgdal", "maptools", "mapproj", "rgeos", "plyr", 
 "RColorBrewer","scales", "viridis", "ggthemes", "tidyverse", "scales", 
 "cowplot","reshape","reshape2", "plotly")
 lapply(x, library, character.only = TRUE)

是的，程序包的功能具有相同的名称。为了避免这种情况，您可以使用packagename::function()。

例如MASS和dplyr都具有称为select的相同功能。

### Example working 
df <- data.frame('may' = letters[1:4], 'be' = 1:4)
library(dplyr) 

df %>% select(may)

## Example not working 
detach('package:dplyr', unload = TRUE)
library(dplyr)
library(MASS)
df %>% select(may)

R中的某些软件包可以抵消其他软件包吗？
