我正在嘗試更改此值
hourlyIntensities_mergedcleannew [1] "12:00:00 AM" "1:00:00 AM" "2:00:00 AM" "3:00:00 AM" "4:00:00 AM" "5:00:00 AM"上午”“上午 6:00:00”[8]“上午 7:00:00”“上午 8:00:00”“上午 9:00:00”“上午 10:00:00”“11:00： 00 AM" "12:00:00 PM" "1:00:00 PM" [15] "2:00:00 PM" "3:00:00 PM" "4:00:00 PM" "5:00 :00 PM" "6:00:00 PM" "7:00:00 PM" "8:00:00 PM" [22] "9:00:00 PM" "10:00:00 PM" "11:下午 00:00”
對此
[1] “12:00 AM” “1:00 AM” “2:00 AM” “3:00 AM” .. 等等
謝謝你
uj5u.com熱心網友回復：
使用gsub,
x <- c("12:00:00 AM", "1:00:00 AM", "2:00:00 AM", "3:00:00 AM", "4:00:00 AM", "5:00:00 AM", "6:00:00 AM")
gsub(':00 '," ",x)
輸出將是
[1] "12:00 AM" "1:00 AM" "2:00 AM" "3:00 AM" "4:00 AM" "5:00 AM"
[7] "6:00 AM"
