About time series graphs, I need help to move on:
A time series of data directly from a data logger comes in the dat
format created below:
year<-c(rep(2005,10))
doy<-c(rep(173,5),rep(174,5))
time<-c(15,30,45,100,115,15,30,45,100,115)
dat1<-c(0.022128,0.035036,0.051632,0.071916,0.081136,0.07837,0.083902,0.
126314,0.080214,0.117094)
dat2<-
c(0.533074667,0.887982667,1.284938,1.845450333,2.145839333,2.145126667,2
.392422,3.60253,2.330776333,3.5277)
dat<-cbind(year,doy,time,dat1,dat2)
dat
time 15 corresponding to 00:15 (past 2400)
I'd like to make a graph illustrating all observation from
the two time series dat1 and dat2
in one graph with different possibilities of labeling the x-axis.
1st wish:
with the date and time drawn on the x-axis every hour (meaning every
fourth observation)
e.g. June 24 01:00, Jun 24 02:00 etc.
2nd example:
with the date label once per 24 hour period
e.g. June 24
I've tried many things and have become very confused on the "ts"
possibilities. Everything I have is
timeseries, so it is very important to get a grip on this.
Please give me a hint.
