Convert h:m:s To/From seconds

hmsToSec - Converts a vector of h:m:s to seconds.

Usage

hmsToMin(x)

hmsToSec(x)

secToHms(x, digits = NULL)

Arguments

x

date-time object for hmsToMin(), vector of times in h:m:s format for hmsToSec(), or numeric vector of seconds for secToHms()

digits

number of decimal places for seconds, an integer from 0 to 15, or NULL. The default uses zero places if all non-missing values have negligible fractional parts, otherwise two. Positive values round fractional seconds with carry into seconds, minutes and hours. For compatibility, digits = 0 discards fractions using floor().

Value

depending on the function:

hmsToMin()

numeric vector of times in minutes

hmsToSec()

numeric vector of times in seconds

secToHms()

character vector of times in h:m:s format

Missing seconds produce NA_character_; infinite values are rejected. Hours can exceed 23. Negative times retain the existing floor-based decomposition (for example, -1 second is -1:59:59).

Details

secToHms - Converts a vector of seconds to h:m:s.
