所以,我有一个小数据框,就像我的标题所说,我想删除所有以某个字母结尾的行,"n".
以下代码将为您提供我正在使用的数据:
url = "http://www.basketball-reference.com/leagues/NBA_1980.html"
library(XML)
x1 = readHTMLTable(url)
east.1980 = x1[["E_standings"]]
west.1980 = x1[["W_standings"]]
east.1980 = east.1980[c(1,2)]
west.1980 = west.1980[c(1,2)]
names(east.1980) = c("Team", "W")
names(west.1980) = c("Team", "W")
wins.1980 = rbind(east.1980, west.1980)
wins.1980$Team = gsub("\\b\\d+\\b", "", wins.1980$Team)
wins.1980$Team = gsub(" +"," ",gsub("^ +","",gsub("[^a-zA-Z0-9 ]","",wins.1980$Team)))
View(wins.1980)
以下是数据框外观的示例:
Team W
1 Atlantic Division ?
2 Boston Celtics 61
3 Philadelphia 76ers 59
4 Washington Bullets 39
5 New York Knicks 39
6 New Jersey Nets 34
7 Central Division ?
