我在SPSS中构建了每小时数据。使用Starttime 7:00和EndTime 7:59。当我在R中读到这些时,我得到了这样的数字:57600& 61140.如何让R将这些值识别为小时数?感谢您的帮助* 强文 *
答案 0 :(得分:1)
我猜您在R
中获得的这些数字是以秒为单位的相应小时数,例如02:51:03 = 2 * 60 * 60 + 51 * 60 + 3 = 10263秒。不符合我猜测的是7:00不是57600秒,但要么是25200秒(am),要么是68400秒(pm)。 57600秒对应16:00(下午4:00)。
如果这些值实际上是秒,那么您可以使用以下函数toHour
将它们转换为时间。
toHour <- function(x, seconds = F) # x is a value of seconds
{
hours <- x %/% 3600
secs. <- x %% 3600
mins <- secs. %/% 60
secs <- secs. %% 60
## add a 0 to single-digit hours / minutes / seconds to make it look nicer
mytime <- c(hours, mins, secs)
for(i in 1:length(mytime))
{
if(length(unlist(strsplit(as.character(mytime[i]), split = ""))) == 1)
{
mytime[i] <- paste(0, mytime[i], sep = "", collapse = "")
}
}
##
if(seconds == T)
{
return(paste(mytime[1], mytime[2], mytime[3], sep = ":", collapse = ""))
}
if(seconds == F)
{
return(paste(mytime[1], mytime[2], sep = ":", collapse = ""))
}
}
toHour(10263, seconds = T) # check function
#[1] "02:51:03" #checked
my_seconds <- seq(57600,61140, 60) # I guess you have no seconds in your time and, so, "my_seconds" is the values you get in R
sapply(my_seconds, toHour) # turn all values (seconds) to hours:minutes
#[1] "16:00" "16:01" "16:02" "16:03" "16:04" ...
sapply(my_seconds, toHour, seconds = T) # turn all values (seconds) to hours:minutes:seconds
#[1] "16:00:00" "16:01:00" "16:02:00" "16:03:00" ...
如果我误解了这个问题或者我的帖子无关紧要,我很抱歉,但由于声誉不佳,我无法在评论中询问详细信息。
编辑:toHour
返回字符值。下一步是:
library(chron)
chron(times. = sapply(my_seconds, toHour, seconds = T))
#[1] 16:00:00 16:01:00 16:02:00 16:03:00 16:04:00 ...
