Hi Rodrigo,<br>
<br>
this is indeed an inconsistency in how FastR was giving out its objects <br>
to other languages. It is fixed in the development version and will be <br>
fixed in the next release: your example should print "[3]" in both cases.<br>
<br>
For more details here is the description from changelog with few notes:<br>
<br>
* R code evaluated via interop never returns a Java primitive type, but <br>
always a vector<br>
* Vectors of size 1 that do not contain NA can be unboxed (i.e. you <br>
should be able to use them in Ruby anywhere where a primitive value is <br>
expected)<br>
* Sending the READ message to an atomic R vector (array subscript in <br>
most languages) gives<br>
* Java primitive type as long as the value is not `NA`<br>
* if the value is `NA`, a special value that responds to `IS_NULL` <br>
with `true`. If this value is passed back to R it behaves as `NA` again<br>
* Note that sending the READ message to a list, environment, or other <br>
heterogenous data structure never gives atomic Java type but a primitive <br>
R vector<br>
* Note: if you want to check for NA, the easiest is Polyglot.eval('R', <br>
'<a href="https://urldefense.proofpoint.com/v2/url?u=http-3A__is.na&d=DwMFaQ&c=RoP1YumCXCgaWHvlZYR8PZh8Bv7qIrMUB65eapI_JnE&r=CUkXBxBNT_D5N6HMJ5T9Z6rmvNKYsqupcbk72K0lcoQ&m=KxgZZsVmXDgdne4GBzI5wekHJC5-Da_qpphJZxr1RuU&s=JkJ67HLUTkzuA4rbPyH0hzj4O0Xf8iw4N0RIYsFjJB4&e=" rel="noreferrer" target="_blank">is.na</a>').execute(myvector) or Polyglot.eval('R', <br>
'<a href="https://urldefense.proofpoint.com/v2/url?u=http-3A__is.na&d=DwMFaQ&c=RoP1YumCXCgaWHvlZYR8PZh8Bv7qIrMUB65eapI_JnE&r=CUkXBxBNT_D5N6HMJ5T9Z6rmvNKYsqupcbk72K0lcoQ&m=KxgZZsVmXDgdne4GBzI5wekHJC5-Da_qpphJZxr1RuU&s=JkJ67HLUTkzuA4rbPyH0hzj4O0Xf8iw4N0RIYsFjJB4&e=" rel="noreferrer" target="_blank">is.na</a>').execute(myvector[0]). Both return a vector of booleans, but in <br>
the second case it will always contain single element.<br>
<br>
Best,<br>
Stepan<br>
