I have two data frames in R as follows:

table 1

Country name HDI GDP
X N/A x_GDP
Y N/A y_GDP

table 2

Name HDI-2018 HDI-2019
X (irrelevant value) x_HDI
Y (irrelevant value) y_HDI
Z (irrelevant value) z_HDI

I want to replace the HDI column in table 1 with the 2019 HDI values in table 2 (by matching the country names). I want to exclude country Z since it is not in table 1. How would I do this in R? Is it possible using library(dplyr)?

THANK YOU!

My wanted output is below:

Country name HDI GDP
X x_HDI x_GDP
Y y_HDI y_GDP

I tried using the merge command, but it merged all columns.
