与记者生成 pptx 文件时，我收到下一条警告消息：
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 = ""))
由于这个问题，我的应用程序有时会失败。有谁知道我能解决吗？？
先感谢您！
