[R] need for help for solving operations in a vector
Hi Petr I do th? calculation left as follows Irrig=qWC1 Irrig [Irrig>HM]=-1 Irrig[Irrig>0]=0 Irrig.tot=-Irrig*6.123 #6.123 is the hydraulic conductivity at saturation And I got the vector needed Cheers Makram Le 28 d?c. 2015 12:15, "PIKAL Petr" <petr.pikal at precheza.cz> a ?crit :> Hi > > On top of answers you have got here is some plotting you need to answer > yourself > > plot(qWC1, col=(c(0, diff(qWC1))>=0 )+1) > > Which from those red points you want to be included in irrigation period? > All of them?

Hi You probably can do also only Irig.tot <- (Irrig>HM)*6.123 to get desired vector without any further typing around. Logical vector can be treated as c(0,1) vector. FALSE equals zero and TRUE equals 1 on calculations. Maybe you shall spend some time reading R intro manual which can serve you as an excellent starting point to learn R. Although it has one hundred pages it is quite readable and you may find it as a best present you found under Christmas tree.
