Hello! So, this is going to seem like a very simple question - I am quite new to R and am having some trouble figuring out little nuances:
I am running a loop that goes through my data and performs a nls parameter estimation on each data set. At the end of the loop, I would like to collect the parameter estimates in ONE SINGLE DATA FRAME or WRITE.TABLE that I can import into excel. Here is my code: for(j in 1:dim(r)[2]){ indiv=r[,j][which(r[,j]>-1)] #removes -1 growth data age.1=age[1:length(indiv)] length.ind=data.frame(age.1,indiv, row.names=TRUE) #data frame of ages and length est.ind=nls(indiv~Linf*(1-exp(-K*(age.1-to))),start=lkt.A,data=length.ind) # von b growth estimate summary=summary(est.ind, correlation=TRUE) #gives parameter estimate values parameters=data.frame("Linf"=coef(est.ind)[1],"K"=coef(est.ind)[2]) #data frame of parameter estimates } if I just type "parameters" I only get the parameter estimates for the LAST individual that was in the loop. How can i combine EVERY SINGLE parameter estimate into a data.frame or something of the sort and then export this set of data into ONE csv file. I can do it using write.table within my loop, but then I get 52 csv files - I would like to avoid this. I hope this makes sense - any help would be GREATLY APPRECIATED!!!! thanks! -- View this message in context: http://r.789695.n4.nabble.com/data-export-HELP-tp2285445p2285445.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
