I am getting this error when trying to knit HTML Document in R Studio using R Markdown:
Make sure your packages are up to date.
Tools -> Check for Package Updates...
I had this problem, and had a bunch of package updates waiting. This fixed it for me.

Suppose I have a large data set(~10 GB) and I want to run a support vector machine or a linear model. Typically when I run these functions, I get an error message: 'Error: Cannot allocate vector of size 308.4 MB'. What is the best way to deal with this? Would creating random subsets and running the models on the individual subsets be a better approach?

I wonder if there is any R package equivalent to MPlus. Thanks in advance.
Depends on what you use MPlus for. For Structural Equation modelling I really like Lavaan. OpenMX and sem are also good packages for it.
But this question does not belong on stackoverflow as it has nothing to do with programming. It should be moved to crossvalidated.com
