I tried:

fixer_convert("EUR", "USD", 1)

but it returns an error

Error in as.POSIXct.default(df$info$timestamp, origin = "1970-01-01", : do not know how to convert 'df$info$timestamp' to class “POSIXct”

Hello,

This error comes up when fixer_historical() function is called. Following is a simple example that can produce this error.

library(fixerapi)

Sys.setenv(FIXER_API_KEY = "<API_Key>")
fixer_historical(date = "2018-05-18")

The reason behind this error is the ifelse() function in fixer_historical(). By default, ifelse() strips all of the attributes of its variables. For example,

> ifelse(is.null(NULL), as.Date("2018-01-01"), 0)
[1] 17532

One way to resolve is to restore the class() of the original variable. Or, you can simply pass the date variable in with as.character().

I can do a pull request for this if you like.

Cheers.
