Hi! As per Thomas' advice, I upgraded R by using "update.packages()" and got the following warning messages:
Warning messages: 1: installation of package 'lmtest' had non-zero exit status in: install.packages(update[, "Package"], instlib, contriburl = contriburl, 2: installation of package 'quadprog' had non-zero exit status in: install.packages(update[, "Package"], instlib, contriburl = contriburl, 3: installation of package 'cluster' had non-zero exit status in: install.packages(update[, "Package"], instlib, contriburl = contriburl, 4: installation of package 'tseries' had non-zero exit status in: install.packages(update[, "Package"], instlib, contriburl = contriburl, Do I need to worry about these messages? Do I need to do something else to complete the upgrade process? Another question: what is the command for renaming an existing variable? Thanks.
