Hello everyone
I'm relatively new in R coding and I have a problem using the function
forrBuilder, from SPOT package.
> fitC <- forrBuilder(xe, ye, 1e-3, 1e2, "optim-L-BFGS-B" , 100,0,1,FALSE)
Error in x - matrix(rep(xmin, s), nrow = s, byrow = TRUE) :
non-conformable arrays
> traceback()
2: spotNormalizeMatrix(fit$X, ymin, ymax, lb, ub)
1: forrBuilder(xe, ye, 0.001, 100, "optim-L-BFGS-B", 100, 0, 1,
FALSE)
this function works well when my data (xe) are in 1D, but now i'm trying in 2D
and i meet a problem which according to traceback() comes from the function
spotNormalizeMatrix. So I tried with the same data and used
spotNormalizeMatrix, and that s works fine (cf below). I dont understand
because i looked into the function forrBuilder & spotNormalizeMatrix, and they
should be able to manage 2D... Did anyone have an idea about this issue?
Thanks in advance
