[R] Syntax for nls optimization function

I am working on minimization of sum of squared errors for a problem that has 2 box-constrained parameters. I got the solution for this problem using "L-BFGS-B" method in optim function using an R code as res<-optim(par=c(parInit), fn=myFunction, method = c("L-BFGS-B"), lower = parMin, upper = par

Is there any way to skip this line with readLines or any other function? I am only hoping that the data after this bad line is good and I can read them if I can skip the bad one. Thank you. HC -- View this message in context: http://r.789695.n4.nabble.com/sqldf-for-Very-Large-Tab-Delim

Re: [R] sqldf for Very Large Tab Delimited Files

N=1.25 million, it wrote 28 files of about 57 mb each. That is a total of about 1.6 GB and then crashed. I tried with other values on N and it crashes at about the same place in terms of total size output, i.e., about 1.6 GB. Is this due to any limitation of Windows 7, in terms of not having the

Re: [R] sqldf for Very Large Tab Delimited Files

Thank you for indicating that SQLite may not handle a file as big as 160 GB. Would you know of any utility for *physically splitting *the 160 GB text file into pieces. And if one can control the splitting at the end of a record. Thank you again. HC -- View this message in context: http://r

Re: [R] sqldf for Very Large Tab Delimited Files

missing something in the above code that is preventing handling of this big 160 GB file? (2) Should this be handled outside of R, if R is becoming a limitation in this? And if yes then what is a possible way forward? Thank you again for your quick response and all the help. HC http://r.789695.n4

[R] stats::decompose - Problem finding seasonal component without trend

Hi R-help, I'd like to extract the seasonal component of a short timeseries, and was hoping to use stats::decompose. I don't want to decompose the 'trend' component so I thought I should call decompose(x,filter=0). I think I've either misunderstood the filter argument or come upon a bug/feature
