r - How do I use alignDaily on POSIX & Date objects? -

when call

aligndaily(dt, include.weekends = false)

i message

error in xy.coords(x, y) : argument "y" missing, no default

str(dt) shows posixct object.

convert posixct timedate function

aligndaily(as.timedate(dt), include.weekends = false)

the reason aligndaily calls align, has forms any, posixct (inherited any) , timedate. any version (and therefore posixct form) looks this

function: align (package timedate) x="any" function (x, ...)  {     .local <- function (x, y, xout, method = "linear", n = 50,          rule = 1, f = 0, ties = mean, ...)      {         ans = approx(x = x, y = y, xout = xout, method = method,              n = n, rule = rule, f = f, ties = ties, ...)         ans     }     .local(x, ...) } 

there's no way force aligndaily send y parameter. work around casting posixct timedate, forcing align run timedate method.
