使用dplyr过滤器过滤多个条件的意外输出

Question

我有一个包含3个变量的数据框：report_epiweek，report_epiyear和Freq_case。

library(dplyr)
library(ggplot2)    
mydata<-data.frame(report_epiweek=c(1,2,3,4,5,6,7,8,9,10,1,2,3,4,5,6,7,8,9,10), 
                       report_epiyear=c(2018,2018,2018,2018,2018,2018,2018,2018,2018,2018,2019,2019,2019,2019,2019,2019,2019,2019,2019,2019), 
                       Freq_case=c(0,0,0,0,0,0,2,6,2,3,4,5,7,8,34,2,0,6,3,1))

我想使用ggplot2生成条形图。我想用2018年的0值（第1至6周）过滤掉几周。我对过滤器功能的理解是，您可以基于多种条件（来自https://suzan.rbind.io/2018/02/dplyr-tutorial-3/）来过滤行：

基于多种条件的过滤 上面的示例基于单个条件返回行，但是filter选项还允许AND和OR样式过滤器：

filter（condition1，condition2）将返回同时满足两个条件的行。

filter（condition1，！condition2）将返回条件一为真但条件2不为真的所有行。

filter（condition1 | condition2）将返回满足条件1和/或条件2的行。

filter（xor（condition1，condition2）将返回仅满足一个条件的所有行，而不是同时满足两个条件的所有行。

mydata %>% 
  mutate(report_epiweek=as.numeric(report_epiweek)) %>% 
  filter(!Freq_case==0 & report_epiyear==2018) %>%
  ggplot(aes(x=report_epiweek, y=Freq_case))+
  geom_col()+
  ggtitle("EpiCurve") + 
  facet_grid(. ~ report_epiyear)+ 
  theme_bw()+ 
  theme(axis.text.x = element_text(angle = 90), legend.position = "bottom", legend.title = element_text(color = "black", size = 8))

这将产生以下图形。

该过滤器似乎正在过滤所有具有report_epiyear为2018的记录，但是我想要一个图表，其中过滤后的记录是那些Freq_case为0且在2018年的记录。这会使我的Freq_case为0在2019年保持不变。 （我将能够看到其他2018年的值）。

我不确定是否只是不了解如何使用过滤器。任何帮助将不胜感激。

Answer 1

您编写的!仅适用于第一个参数（Freq==0）。在条件&的两个部分周围加上括号，以便在用!反转条件之前将它们合并在一起。

mydata %>% 
  mutate(report_epiweek=as.numeric(report_epiweek)) %>% 
  filter(!(Freq==0 & report_epiyear==2018)) %>%
  ggplot(aes(x=report_epiweek, y=Freq))+
  geom_col()+
  ggtitle("EpiCurve") + 
  facet_grid(. ~ report_epiyear)+ 
  theme_bw()+ 
  theme(axis.text.x = element_text(angle = 90), legend.position = "bottom", legend.title = element_text(color = "black", size = 8))

将此添加到构面内。
