## --- Tests ---

## Default
write.fwf(testData)

## NA should be -
write.fwf(x=testData, na="-")
## NA should be -NA-
write.fwf(x=testData, na="-NA-")

## Some other separator than space
write.fwf(testData[, 1:4], sep="-mySep-")

## Justify right for character columns
write.fwf(testData, justify="right")

## Justify right for character columns, track na values
write.fwf(testData, justify="right", na="!")

## With quotes
write.fwf(testData, quote=TRUE)

## With rownames
write.fwf(testData, rownames=TRUE)

## Without colnames
write.fwf(testData, colnames=FALSE)

## Without colnames, with rownames
write.fwf(testData, colnames=FALSE, rownames=TRUE)

## With rownames and colnames and rowCol
write.fwf(testData, rownames=TRUE, rowCol="HI!")

## formatInfo is tested with unit tests
