Perhaps something like:
as.numeric(chron(times.=c('01:23:21','11:12:13')))
[1] 0.05788194 0.46681713

Hello Everyone
I am new to R
I would like to know how to deal with Time Variable. If I have a column of
containing Time data in the format of hh:mm:ss such as 00:56:45, 01:24:36,
01:41:25, and so on......
I could find averages for this column using the Chron package. But now I
need to plot a graph so I need to convert this Time variable to numeric.
My data is as follows:
Activity Time Required
A 00:56:45
B 01:24:36
C 01:41:25
D 01:48:25
E 01:51:25
F 01:55:25
G 01:59:25
and so on..............
total rows in my data are 150
Can someone guide me regarding converting this Time variable to numeric?
Thank you
RanjanV
