Output of fa2latex command from psych causing LaTeX error in pandoc

Question

I am writing a report using knitr in RStudio. Also using the psych package for factor analysis:

```{r, results='asis'}
library(psych)
data(Thurstone)
fa.Thurstone<-fa(Thurstone)
fa2latex(fa.Thurstone)
```

When I run this code chunk it causes an error:

! LaTeX Error: Unknown float option `d'.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.
 ...                                              

l.124 \begin{scriptsize} \begin{table}[htdp]

pandoc: Error producing PDF from TeX source
Error: pandoc document conversion failed with error 43

When I save the TeX code it runs fine in LaTeX, but not in knitr.

Any suggestions on how to resolve this?
