Question

在与记者生成pptx文件时，我收到了下一条警告消息：

Warning: System font `Calibri` not found. Closest match: `DejaVu Sans`

Warning: System font `Times New Roman` not found. Closest match: `TeX Gyre Termes`

Warning: System font `Courier New` not found. Closest match: `TeX Gyre Cursor`

Warning: System font `Symbol` not found. Closest match: `DejaVu Sans`

这是我的代码：

library(ReporteRs)
 informe_ob <- pptx(template = 'plantilla_reporte_ejecutivo_ob.pptx')
  informe_ob <- addSlide(informe_ob,"layout_informe_ob")
  slide.layouts(informe_ob)
  slide.layouts(informe_ob, "layout_informe_ob")
  informe_ob <- addPlot(informe_ob, function( ) print(p1()), vector.graphic = TRUE)
  informe_ob <- addPlot(informe_ob, function( ) print(p2()), vector.graphic = TRUE)
  informe_ob <- addFlexTable( informe_ob, flextable = flex_table_ob())
  informe_ob <- addParagraph(informe_ob,as.character(today))
  informe_ob <- addParagraph(informe_ob,as.character(fecha_titulos))
  informe_ob <- addParagraph(informe_ob,as.character(tabla_ob()))
  informe_ob <- addFlexTable( informe_ob, flextable = flex_entorno())
  informe_ob <- addFlexTable( informe_ob, flextable = flex_colectora())
  writeDoc(informe_ob, paste("Reporte_Ejecutivo_",tabla_ob(),"_",fecha_nombre_informe,".pptx",sep = ""))

由于此问题，我的应用有时会失败。有谁知道我能解决吗??

提前谢谢！

Answer 1

您需要为fontname_serif，fontname_sans，fontname_mono，fontname_symbol指定参数，以便它们指向系统上的现有字体名称。见https://davidgohel.github.io/ReporteRs/reference/addPlot.html

您可以使用gdtools::sys_fonts()获取系统中现有字体的列表。
