Re: [R] Axis whitout all the row, that contains time
Hello,
the time are in the first table like that : 10:24:00
and i use this for
listeMesuresPropres$Heure. <- hms(listeMesuresPropres$Heure.
after time ar like that : 10H 24M 0S
and when i use with ggplot
scale_x_time(breaks = "20 secs",labels = "%H:%M:%S")
it have the graphics but noting write on the X axis.
I think it a problem with the format of the time, because if i try a ggplot
without scale_x_time i don't have anything on the graphic.
Thank's

[R] Axis whitout all the row, that contains time
Hello, i'm using Rstudio from a few day, and i have some information in a CVS file, take every five second, format of the time is HH:MM:SS. I use the hour on the X axis, but i don't want having all the time print. For example only every 10 values. I think it will be possible with scale_x_datetime(breaks = date_breaks(XXX) but i don't understand how select every 20 s.
