[R] non-conformable arrays

[Thierry Onkelinx]

Dear all,

I'm puzzled by this error. When running tcrossprod() within the function it
returns the error message. The code also outputs the object a and b.
Running the tcrossprod() outside of the function works as expected.

        cat("a <-")
        dput(a)
        cat("b <-")
        dput(b)
        cat("tcrossprod(a, b)")
        tcrossprod(a, b)

a <-structure(c(1, 1, 1, 1, 1, 1, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 1), dim = c(10L, 2L), dimnames = list(c("9", "13", "21",
"29", "30", "37", "52", "53", "56", "70"),
c("tmp2028c70ae152b4c63bb7ab902158b408366217581",
"tmp2028c70ae152b4c63bb7ab902158b408366217582")), assign = c(1L,
1L), contrasts = list(tmp2028c70ae152b4c63bb7ab902158b40836621758 =
"contr.treatment"))
b <-structure(c(-0.916362039446752, -0.849801808879291, -0.744535398206787,
0.875896407785924, 0.822587420283086, 0.894210774042389), dim = 3:2)
tcrossprod(a, b)

For those how like a fully reproducible example:
the offending line in the code:
https://github.com/inbo/multimput/blob/e1cd0cdff7d2868e4101c411f7508301c7be7482/R/impute_glmermod.R#L65
a (failing) unit test for the code:
https://github.com/inbo/multimput/blob/e1cd0cdff7d2868e4101c411f7508301c7be7482/tests/testthat/test_ccc_hurdle_impute.R#L10
