解决方案
尝试这个：
#Data
df <- data.frame(Start='2020-07-31 23:06:05.0',
End='2020-08-31 23:06:05.0',stringsAsFactors = F)
#Code
df$Month1 <- format(as.POSIXct(df$Start,format='%Y-%m-%d %H:%M:%S',tz = 'GMT'),"%B")
df$Month2 <- format(as.POSIXct(df$End,format='%Y-%m-%d %H:%M:%S',tz = 'GMT'),"%B")
输出：
df
Start End Month1 Month2
1 2020-07-31 23:06:05.0 2020-08-31 23:06:05.0 July August
