My data.frame is not readable with dygraph - r

Question

I would like to produce dygraph with a data.frame I import from CSV file. I suspect my date column is formatted incorrectly. My date column is originally in %m/%d/%y format.
If applicable, column 1 is class(factor), column 2 and 3 are class(integer). Here is head(mydata)
Date term1 term2
1 7/1/16 2304 0
2 7/2/16 2304 0
3 7/3/16 1628 0
4 7/4/16 1230 0
5 7/5/16 1216 5
6 7/6/16 2056 0
Here is the dygraph command:
library(tidyverse)
library(dygraphs)
dygraph(mydata, main = "mydata") %>%
dyRangeSelector()
I received error: Unsupported type passed to argument 'data'.
I then converted mydata$Date to POSIXct like this:
mydata$DateTime=as.POSIXct(paste(mydata$Date, mydata$Time), format="%Y%m%d %H%M%S")
I expected the above to correct the problem, however I still receive same error. When I view(mydata), I see this:
Date term1 term2 DateTime
1 <NA> 2304 0 <NA>
2 <NA> 2304 0 <NA>
3 <NA> 1628 0 <NA>
4 <NA> 1230 0 <NA>
5 <NA> 1216 5 <NA>
6 <NA> 2056 0 <NA>
Clearly, this only worsened the problem.
I was able to use dygraph on imported stock data, and based on head(my stock data) the correct head(mydata) would look like this:
Date Open High Low Close Volume
2016-02-03 2016-02-02 18:00:00 18.00 18.88 16.000 18.20 4157398
2016-02-04 2016-02-03 18:00:00 18.26 19.42 17.570 18.50 469900
2016-02-05 2016-02-04 18:00:00 18.84 18.88 17.520 17.60 219900
2016-02-08 2016-02-07 18:00:00 17.52 18.00 15.720 15.85 372100
2016-02-09 2016-02-08 18:00:00 15.50 15.50 12.748 12.81 744100
2016-02-10 2016-02-09 18:00:00 13.01 14.00 12.790 13.09 260800
Thank you in advance for everyone's time & insight.
