changing font size for y-axis factor labels
Tiffany Vidal · Mar 4, 2009 · r-help

I am trying to reduce the font size for y-axis labels, not ylab, but the actual categorical names. I have tried cex, cex.axis, cex.lab, font, but none seem to do the trick. Any ideas? thank you.

Hello, I'm trying to make a 3D pie chart, but my labels are overlapping. I see that labelpos could offer a solution to this, but I have been unable to find any code snippets that indicate what type of...

alternate corField (clim.pact) function
Tiffany Smith · May 7, 2014 · r-sig-geo

Hello, I?m looking to produce maps of the correlation between a time series at 1 location to global climate variables (SLP, SST etc). A few years ago I did this using ?corField? from the clim.pact package, but since...

Regional Average of Rasters
Tiffany Smith · Nov 11, 2014 · r-sig-geo

I have a rasterBrick (temp) with global temperatures, and a rasterLayer (regions) of global regions. I would like to create a rasterBrick of regional average temperatures. So far I have the following: region1<-mask(temp,regions,maskvalue=1,inverse=TRUE...

distribution of random effects glmmTMB - covariance structure
Vidal, Tiffany (FWE ) · Sep 6, 2018 · r-sig-mixed-models

I'm unclear about the distributional assumptions regarding the random effects in glmmTMB, using different covariance structures. It is my understanding that the default is unstructured covariance structure. When estimating a vector of random effects, what is the assumption about...

lme4 observation level effects with indicator
Tiffany Vidal · Apr 2, 2016 · r-sig-mixed-models

I am interested in estimating a mixed model with a random effect for year, site, and an observation-level effect to account for overdispersion, assuming Poisson error structure, using the lme4 package in R. Additionally, I have an indicator variable...
