[FLR-list] incompatible units of measurements in FLQuant objects: f + NA

[Havstovan FAMRI]

Hi all,

Trying to work with a FLStock object.
When doing a basic call like:

> plot(stock)
Warning messages:
1: In FLCore:::uom(op, units(e1), units(e2)) :
  incompatible units of measurements in FLQuant objects: f + NA
2: In `[<-.factor`(`*tmp*`, ri, value = c(3, 3, 3, 3, 3, 3, 3, 3, 3,  :
  invalid factor level, NA generated

I get the graph but the warning propagates forward to other function calls
like

eqsr_fit(stock,.....) in packaǵe "msy":

> eqsr_fit(stock,
+    nsamp = 1000,
+    id.sr = "mystock",
+    models = c("segreg"),
+    method = "Buckland")

Warning message:
In FLCore:::uom(op, units(e1), units(e2)) :
  incompatible units of measurements in FLQuant objects: f + NA

The units in the "stock" object are:

> units(stock)
$catch
[1] "tonnes"

$catch.n
[1] "thousands"

$catch.wt
[1] "kg"

$discards
[1] "tonnes"

$discards.n
[1] "thousands"

$discards.wt
[1] "kg"

$landings
[1] "tonnes"

$landings.n
[1] "thousands"

$landings.wt
[1] "kg"

$stock
[1] "tonnes"

$stock.n
[1] "NA"

$stock.wt
[1] "kg"

$m
[1] "NA"

$mat
[1] "NA"

$harvest
[1] "f"

$harvest.spwn
[1] "NA"
