Re: [R] Confused about using data.table package,

Thanks Hadley! While I got your attention, what is a good way to get started on ggplot2? ;) My impression is that I first need to learn plyr, dplyr, AND THEN ggplot2. That's A LOT! Suppose i have this: iris iris2 <- cbind(iris, grade = sample(1:5, 150, replace = TRUE)) iris2 I want to have

Hello All, I am writing a package. I would like to encourage the user to look at the data to rectify errors with function A before utilizing function B to code these data as binary. I thought about solving this problem by adding a "flag" in the attributes that could be used downstream in B, and

Yes, I mean "won't annoy the user", will allow them to do anything they need to do with a dataframe (write to csv, etc.), but will allow me to test for in a down stream function of the analysis to stop the function and present an error. Adding something to the class attribute seems like the right

Re: [R] Make sure a data frame has been "fun through" a function

Yes. To elaborate a bit on Ista's reply: A) The only way I can imagine hiding info from a user would be to encrypt it. This could be done programmatically I think, but I would have to research it to figure out how. B) If all you want to do is prevent the info from being printed, just create

Re: [R] Make sure a data frame has been "fun through" a function

It depends on what you mean by 1). If you mean "won't annoy the user" then yes, e.g., add something to the class attribute. If 1) means "can't be discovered by the user" then no (at least not easily). Anything you can see they can see. Best, Ista On Feb 20, 2017 4:21 PM, "stephen sefick"

Not by the mail server as such, no, at least not for that reason. However, T-bird likely sends .txt as text/plain and .R as application/octet-stream (or so) and _therefore_ the server eliminates the latter and lets the former pass. -pd > On 20 Feb 2017, at 15:45 , Rui Barradas
