问题描述
我已经从 https://www.kaggle.com/aungpyaeap/supermarket-sales
下载了一个数据集我正在尝试过滤分支 A 上的数据，以便为分支 A 制作折线图。当我运行下面的代码时，输出是很多 NA 值。我已经检查了数据集中的 NA 和 Null 值。任何有关如何正确过滤分支 A 的帮助将不胜感激。
数据集的头部 -
`Invoice ID` Branch City `Customer type` Gender `Product line` `Unit price` Quantity `Tax 5%` Total Date Time Payment cogs `gross margin percentage` `gross income` rating

代码-
library(readr)
dataset <- read_csv("dataset.csv",col_types = cols(Date = col_date(format = "%m/%d/%Y"),Time = col_time(format = "%H:%M")))
View(dataset)
df<- dataset
sum(is.na(df))
sum(is.null(df))
df_filter_A <- filter(df,Branch == "A")
head(df_filter_A)
解决方法
我卸载了 R，现在代码可以正常工作了。我相信这与图书馆有关。我按照这个帖子卸载-
How to uninstall R and RStudio with all packages,settings and everything else?。
感谢您的帮助并查看我的代码。
