How does rCharts deals with dates

[pachevalier]

I'd like to draw a simple time series plot. I have a date variable and a numeric variable. But when I try to do the graph using rCharts, it doesn't recognize my date variable as a date. Here is my gist file https://gist.github.com/blaquans/7140811

Do you have any solution ?

Very good question. We are working towards a more universal implementation of the R to JS date conversion as referenced by #43 , but as of now, each of the JS libraries handles dates differently. For Rickshaw as shown in your example, this will work.

require(rCharts)
fake  <- data.frame(date = seq(as.Date("1990-01-01"), as.Date("1991/01/01"), by = "day"))
fake$x  <- rnorm(nrow(fake))
str(fake)
fake$d  <- as.numeric(as.POSIXct(fake$date))
r <- Rickshaw$new()
r$layer(x ~ d, data = fake, type = "line")
r$show()

@ramnathv wrote a little function to ease the conversion for Rickshaw.

In general JS likes dates in as.numeric(as.POSIXct(myRdate)) * 1000. Hope this helps. Please let us know if it does not.
