发帖数: 14 | 1 I am using Chron package to compute summary statistics for a time variable
with this format 01:34:24,
I submitted the follow scripts:
timemax<-max(x)
timemin<-min(x)
timesd<-sd(x)
timemean<-mean(x)
All the functions return the correct results except the standard deviation
one, I get a tiny number 0.011.
I searched online but could not find others’suggestions about using this
package for SD computation, did I do anything incorrectly?
Thanks. |
