英文:
Convert Seconds to Hours in R
问题
我有一个以秒为单位的列，我想将其转换为小时。最好是将小时以小数格式表示，例如8.5小时，而不是将小时和分钟分开列出。任何帮助将不胜感激。
英文:
I have a column that is in seconds and I want to convert it into hours. I preferably want the hours into a decimal format such as 8.5 hours instead of hours and minutes in separate columns. Any help would be much appreciated.

以下是翻译好的部分：
这里有两种方法。如果x是一个向量，这两种方法也都适用。第一种方法利用一小时有3600秒这一事实。第二种方法较长，但不使用特殊数字。不需要使用任何包。
x <- 30600 # 测试数据
x / 3600
## [1] 8.5
as.numeric(as.difftime(x, units = "secs"), units = "hours")
## [1] 8.5
英文:
Here are two methods. Both also work if x is a vector. The first uses the fact that there are 3600 seconds in an hour. The second is longer but does not use special numbers. No packages are used.
x <- 30600 # test data
x / 3600
## [1] 8.5
as.numeric(as.difftime(x, units = "secs"), units = "hours")
## [1] 8.5
