plot axis appearance problem
Hello, When I plot any data with simple plot command in R, for example :- plot(time,co2,ylim=c(350,380),xlim=c(1993,2003),xlab=NA,ylab=NA,type="p",col=5) Then the first value of x-axis(350) and y-axis(1993) never starts from origin, always they sifted from the origin. Is there any command that I can correct this in the ploted figure and both the axis values start from origin.
