如何在R中过滤一系列数字? [英] How do I filter a range of numbers in R?

问题描述

假设我有如下所示的数据框Mydata:

Let's say I have the data frame Mydata as shown below:

Mydata <- data.frame(x = c(1, 2, 3, 4, 5, 6, 7, 8, 9, 10),
                     y = c(20, 30, 45, 54, 65, 78, 97, 102, 123, 156))

我要过滤此数据帧并创建另一个数据帧，以便仅显示3和7之间的x值及其对应的y值.我尝试了以下操作:

I want to filter this data frame and create another data frame, so that only the values of x between 3 and 7 and their corresponding y values are shown. I attempted the following:

new_frame <- Mydata %>% filter(x == (3:7))

这不起作用.然后如何过滤指定范围?

This didn't work. How then would I filter for a specified range?

提前感谢所有帮助

推荐答案

使用%in%

library(dplyr)
new_frame<- Mydata%>% filter(x %in% (3:7))
new_frame
#   x  y
# 1 3 45
# 2 4 54
# 3 5 65
# 4 6 78
# 5 7 97
