Issues with data.table

[cmhh]

I've noticed I get errors when using data.table with functions such as hc_add_series. I imagine this is because hc_add_series.data.frame is dispatched, and doesn't work quite right if the data.table package is loaded. A simple fix is to always pass in data.frame(dt), but I wonder if this could be handled explicitly within the package? Perhaps by adding hc_add_series.data.table, for example.

Hi @cmhh

Ooops. Thanks. I will fix this at home ;)!

I run:

library(data.table)
library(highcharter)

dt <- data.table(x=rep(c("b","a","c"),each=3), y=c(1,3,6), v=1:9)
head(dt)


hchart(dt, "scatter", hcaes(x = v, y))

highchart() %>% 
  hc_add_series(dt, "scatter", hcaes(x = v, y))

Can we check your sessionInfo?

Sorry. This looks like my mistake. We have two Linux servers at work--one had 0.4.0 on it and the other had 0.5.0, and I didn't realise (or check). The error occurs in 0.4.0, but not 0.5.0.

No problem

Not sure what the protocol is regarding commenting on a closed issue...

It turns out it wasn't the highcharter version at all. It seems that this happens when the dtplyr package is loaded:

library(data.table)
library(highcharter)

dt <- data.table(x=rep(c("b","a","c"),each=3), y=c(1,3,6), v=1:9)

hchart(dt, "scatter", hcaes(x = v, y))

library(dtplyr)

hchart(dt, "scatter", hcaes(x = v, y))

After loading dtplyr, I get the following error:

Error in UseMethod("select_") : 
  no applicable method for 'select_' applied to an object of class "NULL"

I guess this is some sort of masking issue related to dtplyr?

Cheers

Don't worry,

I will look into it to see what happens ;).

Hi @cmhh

Internally, I forced to be only a data.frame class, and in my test this work well. Please test to check in your enviorment.

Thanks

I'll close the issue. If you still have problem we can reopen.
