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. Time series beginner - Anette [[alternative HTML version deleted]]
