R - how to load each file from folder
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;

I have a folder and that contains a lot of R files, that files are functions actually. What I need is to create code in another project in R which will load each file in that folder and load this functions in to the environment.
I know that better option is to create a R package from this functions but it can´t be done for several reasons in my case.
What is the simplest way to achieve my goal?

What exactly are the several reasons you can't make a package? Have you tried anything at all yet? Where exactly are you getting stuck? Presumably you just want to runsource()on each of those files? Did you try something likeMap(list.files("folder/.*R"), source)?

Oops, got my parameters mixed up, it should be more likeMap(source, list.files(path="myfolder", pattern="R$"))

Hi, Im still getting this errorError in file(filename, "r", encoding = encoding) : cannot open the connection In addition: Warning message: In file(filename, "r", encoding = encoding) : cannot open file 'active_payment_promises.R': No such file or directoryI dotn´t know what is wrong, it says that directory doesn´t exsists but active_payment_promises is actually my function there and it loaded it
