问题描述
我使用R函数list.files来获取文件夹中的文件列表。我还想记录每个文件的创建,修改和访问时间
我该怎么做?我试图谷歌搜索,但没有发现任何有用的命令
下面的截图是从我的Windows机器。我得到它时,我右键单击文件名称,然后单击属性
##使用单个路径
p <-R .home()
file.info(p)$ ctime
#[1]2014-11-20 08:15:53 PST
##使用向量多个路径
paths< - dir(R.home(),full.names = TRUE)
tail(file.info(paths)$ ctime)
#[1]2014 -11-20 09:00:45 PST2014-11-20 09:00:47 PST
#[3]2014-11-20 09:00:47 PST2014-11- 20 09:00:50 PST
#[5]2014-11-20 09:00:33 PST2014-11-20 09:00:33 PST
I am using R function list.files to get a list of files in a folder. I would also like to record when each file was created, modified and accessed
how can i do that? i tried google search, but didnt find any useful command
Below screenshot is from my Windows machine. I get it when i right click a file name and click "properties"
解决方案
Check out file.info()
for this and other file properties:
## With a single path
p <- R.home()
file.info(p)$ctime
# [1] "2014-11-20 08:15:53 PST"
## With a vector of multiple paths
paths <- dir(R.home(), full.names=TRUE)
tail(file.info(paths)$ctime)
# [1] "2014-11-20 09:00:45 PST" "2014-11-20 09:00:47 PST"
# [3] "2014-11-20 09:00:47 PST" "2014-11-20 09:00:50 PST"
# [5] "2014-11-20 09:00:33 PST" "2014-11-20 09:00:33 PST"
