Description Usage Arguments Details Value Author(s) Examples

A convenience function for writing the names and values of objects to the session window (and/or to another object). Especially useful to keep track of variables within loops.

1	pvar(..., digits = NULL, abbrev = NULL, sep = ";", verbose = TRUE)

`...`	Objects whose names and values are to be printed, separated by commas. Can also be a simple list.
`digits`	Number of digits to display for numeric objects. Defaults to `NULL`, which corresponds to no restriction on the number of digits. This is passed to the `digits` argument of `round`.
`abbrev`	Number of characters to display for character objects. Defaults to `NULL`, which corresonds to no restriction on the number of characters.
`sep`	Character string that separates the objects that are printed
`verbose`	`=TRUE` writes the value of the object(s) to the session window

Input objects can be numeric, character, and/or logical. They can also be atomic or vectors. It will accept data frames and matrices without error, but the results won't be easily readable.

Invisibly returns a character string containing the names of the objects and their values

x <- 10
y <- 20.728923
z <- "This.long.string"

pvar(x, y, z)
pvar(x, y, z, digits = 2)
pvar(x, y, z, abbrev = 4)
pvar(x, y, z, digits = 2, abbrev = 4)
pvar(x, y, z, sep = ",")

# values can be vectors too
x <- 10:12
y <- c("This","That")
v2 <- pvar(x, y, verbose = FALSE)
v2

# Or a simple list
pvar(list(x = 1:2, y = "this", z = TRUE))

# Can be useful for keeping track of iterations in loops

  for (j in letters[1:2]) {
    for (k in c("this","that")) {
      pvar(i, j, k)
