森林图展示回归分析的结果

通过conda安装纯净环境的forestplot

  • conda create -n forestplot -c conda-forge r-base=4.1.3
  • conda activate forestplot
  • conda install -c conda-forge r-tidyverse=1.3.1 -y
  • conda install -c conda-forge r-irkernel -y
  • conda install -c conda-forge r-forestplot -y
  • Rscript -e “IRkernel::installspec(name=’forestplot’, displayname=’r-forestplot’)”
