This function is a wrapper around the functions dim for the number of
rows and columns, names for the variable names, df.head for the
first rows, and df.tail for the last rows of a data frame.
df.check(x, print = c("dim", "names", "head", "tail"), n = 4,
digits = 3, width = 20, row.names = TRUE, row.names.col = "gray2",
message = TRUE, message.col = "b.blue", check = TRUE, output = TRUE)a data frame.
a character string or character vector indicating which
results to show on the console, i.e., "dim", for
the number of rows and number of columns, "names"
for the variable names, "head" for the first rows
of the data frame, and "tail" for the last rows
of the data frame.
a numeric value indicating the number of rows to be printed on the console.
a numeric value indicating the maximum number of decimal places to be used.
a numeric value indicating the maximum width of the character strings in the vector.
logical: if TRUE, row names of the data frame are
printed on the console.
a character string indicating the text color for the row
names, see color argument of the chr.color
function.
logical: if TRUE, number of remaining rows and
