comment Is it better to use MAE or MSE for perfomance measure?
The point is that you make such plots for RF and SVM, go to your forest people and discuss which distribution of error suits them better. This way you will do a rational choice between methods, not some random-people-on-the-internet-told-me-that-one-number-is-more-magic-than-other thing.

The code for the example plot is just plot(abs(predicted-true)~cut2(true,g=10)); only the Hmisc package is needed to be installed and loaded first.

comment K-fold validation, how to use MSE and STD for model selection
You can do a Wilcoxon test or t-test (after appropriate normal distribution check) using per-fold MSE sets as compared samples; it is likely that it will tell you that models are statistically indistinguishable, thus that model selection in this context is pointless.
