The ggplot2 theme we are using (theme_bw()) is already in line with Tufte's recommendations, but we could still eliminate the panel grids in the plot above. In order to achieve that, use the theme() function and pass two arguments to it, panel.grid.minor = element_blank() and panel...
Visualizations of results were performed using the packages “ggplot2” and “effects”47,48. Main analysis (Supplementary Table 2): For each response variable/scale combination, we used the interaction of block (for local and turnover scale only), site and study as random effect. The random ...
