How to control table placement on a page

I am producing a PDF document .using R Markdown and tinytex. The latex engine is xelatex. I want to know how to control table placement on the page.
In the example below, I create a bit of two column output, display some text and a map in the two columns The next chunk outputs a table (in a single column).. I want the table to be under the two-column output, but is is currently sitting at the bottom of the page. (this example has multiple UCF calls, they all work. I am more concerned with putting the output chunks on a page.)

BEGIN CODE:

Demographic and Economic Profile for r placeName

r if(outStats) '## Basic Statistics'

\bminione #Code that starts the two-column output (works)

    if(outStats) {
      cat(baseText(placeName))
    }

\emini
\bminitwo

if(outStats){
   y <- cp_countymap(substr(fips5,3,5))
   print(y)
   }

\emini #End of two-column output
\FloatBarrier

if(outStats){
  x <-  statsTable1(cty=fips5, 
                             place="",
                             sYr=2010,
                             eYr= oYr,
                             ACS=oACS,
                             oType="latex")
   print(x)
   }

END CODE
Any ideas how to control where the outputs of the R markdown chunks sit on the page?

TIA
