Examples

# overviews of data.frames:
ovv(mtcars)
ovv(iris)

# overviews of matrices:
ovv(as.matrix(mtcars))
ovv(as.matrix(iris))

# overviews of tables:
library(magrittr) # for %>%
library(lubridate) # for ymd, isoweek, isoyear
# a fonction used to create the data set below:
fct <- function(y) {
g <- function(x, y) ymd(as.integer(paste0(y, x)))
  start_end <- lapply(c("0101", "1231"), g, y)
  seq(start_end[[1]], start_end[[2]], by = "day")
}
# creating a fake data set:
cal <- 10:17 %>%
  lapply(fct) %>%
  do.call(c, .) %>%
  (function(x) lapply(list(isoweek, isoyear), function(f) f(x))) %>%
  do.call(cbind, .) %>%
  as.data.frame %>%
  setNames(c("week", "year")) %>%
  unique
# an overview of its table:
ovv(table(cal))

# A SpatialPointsDataFrame
library(sf)
stations <- as(imhen::stations, "Spatial")
stations
class(stations)
ovv(stations)
