The vignette code isn't working in my laptop, for some reason.

Also if I don't set this: Sys.setenv(TZ='GMT')
the makeUrls functions crashes, outputs this error:
Error in as.POSIXlt.character(x, tz, ...) :
character string is not in a standard unambiguous format

Here is the code and it's output in the console, the main error is in the end of the code:

db <- src_sqlite("pitchfx.sqlite3", create=TRUE)
scrape(start="2015-06-08", end=Sys.Date(), connect=db$con)

Thanks for the report! Could you also include your sessionInfo()?

Also, it might be nice to know what this gives you:

@martinbel I think if you do

scrape(start = "2015-06-08", end = as.character(Sys.Date()))

instead of

scrape(start = "2015-06-08", end = Sys.Date())

it should work?

@martinbel please re-open if this doesn't fix the problem ^^^

I'm currently receiving this error when using scrape().

require(data.table)
require(pitchRx)
require(RSQLite)
require(dplyr)

startDate <- "2015-09-13"
endDate <- "2015-09-15"

test <- scrape(startDate, endDate) # this works fine

db <- src_sqlite("pitchfx.sqlite3", create=TRUE)

scrape(startDate, endDate, connect = db$con)

If file names don't print right away, please be patient.

This same error occurs if I use a MySQL() database instead of the sqllite one.

db = dbConnect(MySQL(), user=username, password=password, dbname=dbname, host=host)
scrape(startDate, endDate, connect = db$con)

I'm a bit stumped on this one, does anyone know what the issue could be?

Thanks for building this package Carson it's so awesome.

@efbbrown I think this is due to a different problem. Could you re-post this as a new issue and include output from devtools::session_info()?

Sorry Carson no problem, reposted now in its own issue # 33.

Cheers.
