Optimization problems

[AridaiHari]

Hello, I used the code below for optimization with the GA package , but I have been getting errors.

dir.create(file.path("./Optimized")) dir.create(file.path("./Optimized", "07042020"))
write.dir <- "./Optimized/07042020"

Optimization

GA.inputs_All <- GA.prep(method = "AIC", ASCII.dir = CVM, Results.dir = write.dir, min.cat = 0,
select.trans = list("A", NA , "A", "A", "A", "A", NA, "A", "A", "A", "A", "A"), parallel = 4)

And it produces this warning:

Warning message: In dir.create(file.path(Results.DIR, "Plots")) : cannot create dir '.\Optimized\07042020Results\Plots', reason 'No such file or directory'

the code creates 07042020, Results and tmp directories but not Plots.

I hope I can have an answer. Thank you!

Not certain, but I might suggest specifying the full directory rather than a relative path to your write.dir. This ultimately shouldn't matter, but may be the issue in this case.

Actually I tried the complete path but the error is still the same

CVM<-stack("C:/Users/Gabriela/Documents/CutByLadera/CVM_stack.tif") dir.create(file.path("C:/Users/Gabriela/Documents/CutByLadera/Optimized")) dir.create(file.path("C:/Users/Gabriela/Documents/CutByLadera/Optimized", "07042020"))

write.dir <- "C:/Users/Gabriela/Documents/CutByLadera/Optimized/07042020"

GA.inputs_All <- GA.prep(method = "AIC", ASCII.dir = CVM, Results.dir = write.dir, min.cat = 0,
select.trans = list("A", NA , "A", "A", "A", "A", NA, "A", "A", "A", "A", "A"), parallel = 4)

Warning message: In dir.create(file.path(Results.DIR, "Plots")) : cannot create dir 'C:\Users\Gabriela\Documents\CutByLadera\Optimized\07042020Results\Plots', reason 'No such file or directory'

Specify the full path, ending with a forward slash. write.dir <- "C:/Users/Gabriela/Documents/CutByLadera/Optimized/07042020/"
