Other options are "rle", "lzw", "jpeg", "zip", "lzw+p" and "zip+p". This function allows you to set the compression type, which defaults to "none", with the compression argument.
Last, you can save a plot to TIFF (Tagged Image File Format) with the tiff function. Crooked images can be straightened using Deskew when converting to PDF. Several images can be combined into one PDF with 'Merge' (optional). If needed, you can set the language of the text as well (optional). With 'Use OCR' in the optional settings, you can extract text from an image. Third, you can save a plot to BMP (Windows bitmap) with the bmp function. Choose a document format from the drop-down menu. Second, for saving plots in JPEG, you can use the jpeg function, which also allows you to set the quality of the image as percentage with the quality argument (75% by default). This image file format is known to weight less than JPEG with better quality, as it supports transparent backgrounds.
If you set the graphic device to a high-resolution ( res = 200), you will need to modify height and width of the corresponding function and the margins of your plot with the par function in order to avoid losing the original formatting and layout.įirst, the png function allows you to save an image to a Portable Network Graphics file. Note that you can convert inches to centimeters dividing by 2.54. Width = 8, height = 7, # Width and height in inchesĬolormodel = "cmyk" # Color model (cmyk is required for most publications) You can also change the width and height (in inches) of the output plot, the paper and point size, or modify the background color, as the PDF plot will have a transparent background, or the color model, among other graphical parameters. However, if you need to edit the image after saving in order to add some decoration or perform some modifications you should use SVG.įirst, in order to save a plot as PDF in R you will need to open the graphics device with the pdf function, create the plot you desire and finally, close the opened device with the dev.off function. The PDF format for saving images is the most used for creating scientific documents, as they are easy to add to LaTeX and maintain the resolution even if you zoom in. Save plot in R as PDF, SVG or postscript (PS)
