Check if a variable is xts or data.frame
dataframe, r, types, xts
Solution
It is a general practice to add `is.smth` and `as.smth` functions for these types of checks and conversions:
df <- data.frame()
xt <- xts()
is.data.frame(df)
[1] TRUE
is.data.frame(xt)
[1] FALSE
is.xts(df)
[1] FALSE
is.xts(xt)
[1] TRUE
Problem
Well the question says it all..I want to check in one of my functions if a function parameter given is of xts or data frame type. How can I do this?
