[R] about data format in R

[lily li]

Hi R users,

I'm trying to read in data, and then plot time series data. However, I have
some problems. In my dataset, the first column represents time, and in the
format:
mm/dd/yyyy-hr:min:sec; For example, 10/01/1995-00:00:00,
10/01/1995-06:00:00, etc.

df:
           date                    evap     precip    intercept
10/01/1995-00:00:00       1.5          2            0.2
10/01/1995-12:00:00       1.7          2.2         0.1
10/02/1995-00:00:00       1.5          1.8         0.3
...

My code is like this
file1 = read.table('df', head=T)

When I read in data, I found that it read incorrectly. How to format when
read in data? Thanks.
