Call a single cell of LaTeX Table - latex

Question

I would like to call a single value from a table inside a textbody.
% latex table generated in R 3.5.1 by xtable 1.8-3 package
% Wed Dec 12 13:56:07 2018
\begin{table}[ht]
\centering
\begin{tabular}{rrrrr}
\hline
& Estimate & Std. Error & z value & Pr($>$$|$z$|$) \\
\hline
(Intercept) & -1.819 & 0.926 & -1.964 & 0.050 \\
hiveH2 & 2.418 & 0.951 & 2.542 & 0.011 \\
nectar+ & 0.827 & 0.947 & 0.873 & 0.383 \\
\hline
\end{tabular}
\label{tab:x}
\end{table}
I would like to be able to write something along the line:
The z value of Hive~2 is \call{tab:x{z value}{hiveH2}}.
That should compile as:
The z value of Hive 2 is 2.542.
the LaTeX table was generated with a R script (neither R markdown nor R sweave):
