Question

Ich bin die nächsten Warnmeldungen erhalten, wenn pptx Datei mit Reportern zu erzeugen:

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` 

Und dies ist mein Code:

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 = "")) 

Meine app manchmal aufgrund dieser versagt Problem. Weiß jemand, kann ich es lösen?

Vielen Dank im Voraus!

Sie müssen Argumente für fontname_serif, fontname_sans, fontname_mono, fontname_symbol spezifizieren, so dass sie zu den bestehenden Font-Namen auf Ihrem System zeigen. Siehe https://davidgohel.github.io/ReporteRs/reference/addPlot.html

Sie können eine Liste der vorhandenen Schriftarten auf Ihrem System mit gdtools::sys_fonts() erhalten.
