Hi , I have a data set and I am trying to get the nonlinear least-squares estimates of the nonlinear model parameters . I have tried nls, gls but seems like i am not able to get it to work. I have attached the data set. This is how I am doing. plz lemme knwo how to get it to work Thanks mlo.1 <- as.matrix(read.table("sio_co2_mlo_trans.txt",header=T)) y.ppm<-mlo.1[,"mlo"] t2.yr<-mlo.1[,1] + mlo.1[,2]/13 #decimal fraction mlo.input<-data.frame(mlo.ppm=mlo.1[,"mlo"],t2.yr=t2.yr) mod<-nlsModel(y.ppm ~ (C1 + C2 * exp(C3 * t2.yr) + (1 + g * t2.yr) * (a1 * sin(2*pi*t2.yr) + b1 * cos(2*pi*t2.yr)+ a2 * sin(4*pi*t2.yr) + b2 * cos(4*pi*t2.yr) + a3 *sin(6*pi*t2.yr) + b3 * cos(6*pi*t2.yr) + a4 * sin(8*pi*t2.yr) + b4 * cos(8*pi*t2.yr))), data=as.data.frame(mlo.input),start=list(C1=250,C2=20,C3=.05, g=.04,a1=1,b1=1,a2=1, b2 =1, a3=1, b3=1, a4=1, b4=1)) =============================using gls ( I dont know how to make the above long equations work in gls. fm1<-gls(y.ppm ~ t2.yr + sin(2*pi*t2.yr) + cos(2*pi*t2.yr), data=as.data.frame(mlo.input)) On 5/10/06, Gabor Grothendieck <ggrothendieck at gmail.com> wrote:> > Try this: > > pmax(tmax.m[,1], tmax.m[,2], na.rm = TRUE) > > > On 5/10/06, Dale Steele <Dale_Steele at brown.edu> wrote: > > Hello -- Given the 10x2 matrix below, my goal is to create a vector > > which contains the maximum of column 1 and column 2, or the only value > > if there is an NA in one column.
