How to describe the data structure of a data frame in R? -

-

i looking way describe data structure (not data itself) of data frame in r.

df = read.csv2('data.csv') desc(df)

output should 

 df.columnname1  df.columnname2 (type)  ...

try:

df_types <- data.frame("col_types" = unlist(lapply(df, typeof)))

i use lapply loop on columns getting type. output named list, use unlist convert named character vector , cast data.frame printed output in format you're after.
