Package Dependencies
(Note that a script is not a package.) When you run your script analyzer.R it explicitly loads base64enc so the package is in your load path. But your package may just have Imports: base64enc with a corresponding NAMESPACE statement -- that makes the code from base64enc available in you package...
Error in R using neuralnet package
I don't see y column, that you're referring in your formula, in your data set. Your target variable should exist in your data set. Should it be SP500_R? Second, neuralnet won't work with NAs in data, filter your data set with na.omit() first. Also, let me give a side note:...

How to use S3 methods from another package which uses export rather than S3method in its namespace without using Depends or library()

R deepnet package: how to add more hidden layers to my neural network?
r,neural-network,deep-learning,r-package
Although I am unfamiliar with the deepnet package, it appears it is structured the same as other neural net packages. After looking at the documentation (?sae.dnn.train) you will see: hidden: vector for number of units of hidden layers.Default is c(10). Now this isn't the clearest description but I believe it...

How do I get rid of the NOTE's generated by R CMD check when using for example ddply in my package?
r,warnings,plyr,r-package,package-development
There are several workarounds. The easiest is to just assign NULL to all variables with no visible binding. VarA <- VarB <- VarC <- VarD <- VarE <- NULL A more elegant solution is to use as.quoted and substitute. UPDATE by @Dr. Mike: the call to as.quoted need to be...
