r - How to convert two variables (integers) to a double in R?

Question

I have never used R before and haven't found good docs on is.numeric() or double() online.

Very simply, I am trying to take two integers and put them in a double, which I want to put in a vector, which will enter as a column. I'm trying to solve the former part.

endlat <- df[i, "end.station.latitude"]
endlong <- df[i, "end.station.longitude"]
end <- as.double(endlat, endlong)

This only stores one of the values in the variable. How does this function work?

Answer 1

你想要

as.double(c(endlat, endlong))

这会将包含和的整数长度为 2 的向量传递给，它只接受一个参数。endlatendlongas.double
