Re: [R] Convert date to continuous variable in R

Looks good, but there are some ways in which I think you’re making it more complicated than necessary. Two calls to plot(), with plot.new() in between, is definitely not needed. Recalculating LAI_simulation$Date three times should not be needed. ## create example data day0 <- as.Date('2009-10-7'

Re: [R] Convert date to continuous variable in R

Thanks it worked for me. I wanted to plot days since planting on x-axis 1 and years on x-axis 3. LAI_simulation$Date <- as.Date( LAI_simulation$Date, '%Y/%m/%d') LAI_simulation$Date <- as.integer(LAI_simulation$Date - as.Date("2009-10-07")) plot(LAI~Date,data=LAI_simulation,xlab="Days since Oct, 7

[R] Convert date to continuous variable in R

How can I convert date to continuous variable staring from 1. I tried as.numeric but R starts counting from default January 1, 1970 while my data start Oct 7, 2009. I need to do this conversion to plot the date on two x-axes (1 and 3). Ex; Date LAI 10/7/2009 0 10/8/2009 0.004173 10/9/2009 0.009997
