### Simple test of print.xtableMatharray
print.xtableMatharray(xtable(V, display = rep("E", 4)))

class(V) <- c("xtableMatharray")
class(V)

### Test without any additional arguments
mth <- xtable(V)
str(mth)
print(mth)

### Test with arguments to xtable
mth <- xtable(V, display = rep("E", 4))
str(mth)
print(mth)

mth <- xtable(V, digits = 6)
str(mth)
print(mth)

### Test with additional print.xtableMatharray arguments
mth <- xtable(V, digits = 6)
str(mth)
print(mth, format.args = list(decimal.mark = ","))
print(mth, scalebox = 0.5)
print(mth, comment = TRUE)
print(mth, timestamp = "2000-01-01")
print(mth, comment = TRUE, timestamp = "2000-01-01")
