predict by VAR analysis

In some cases, as VAR predict function's output  all implied data on the console, it may take extra time to find the data of focus. Specifying attribute as below suppresses unnecessary outputs.

>predict(VAR(v_XCPG_1992_2016),lag=6)$fcst$<tag of focus data>

Below will help to understand output's data structure.

>predict(VAR(v_XCPG_1992_2016),lag=6)[1]
>predict(VAR(v_XCPG_1992_2016),lag=6)[2]
>predict(VAR(v_XCPG_1992_2016),lag=6)[3]

Please see the sample outputs.

> predict(VAR(v_XCPG_1992_2016),lag=6)$fcst$GDP
