custom_create_PDF {baRcodeR}

R Documentation

Make QR codes and print labels

Description

Input a vector or data frame of ID codes to produce a PDF of QR-coded labels that can then be printed. The PDF setup is for the ULINE 1.75" * 0.5" WEATHER RESISTANT LABEL for laser printer; item # S-19297 (uline.ca)

Usage

custom_create_PDF(user = FALSE, Labels = NULL, name = "LabelsOut",
  ErrCorr = "H", Fsz = 2.5, Across = TRUE, ERows = 0, ECols = 0,
  trunc = TRUE, numrow = 20, numcol = 4, page_width = 8.5,
  page_height = 11, width_margin = 0.25, height_margin = 0.5,
  x_space = 215, y_space = 182)

barcode_make(Labels, trunc, ErrCorr, x_space, y_space, Fsz)

Arguments

`user`	logical. Run function using interactive mode (prompts user for parameter values) Default is `FALSE`
`Labels`	vector or data frame object containing label names (i.e. unique ID codes).
`name`	character. Name of the PDF output file. Default is `"LabelsOut"`.
`ErrCorr`	error correction value. Level of damage from low to high: `"L"`, `"M"`, `"Q"`, `"H"`. Default is `"H"`
`Fsz`	numerical. Sets font size using a number between `2.2` and `4.7`. Longer ID codes may not fit on the labels using larger font sizes. Default font size is `2.5`
`Across`	logical. When `TRUE`, print labels across rows, left to right. When `FALSE`, print labels down columns, top to bottom. Default is `TRUE`.
`ERows`	number of rows to skip. Default is `0`. Example: setting ERows to 6 will begin printing at row 7. ERows and ECols are useful for printing on partially-used label sheets.
`ECols`	number of columns to skip. Default is `0`. Example: setting ECols to 2 will put the first label at column 3. ERows and ECols are useful for printing on partially-used label sheets.
`trunc`	logical. Text is broken into multiple lines for longer ID codes, to prevent printing off of the label area. Default is `TRUE`.
`numrow`	numerical. Number of rows per page. Default is `20`.
`numcol`	numerical. Number of columns per page. Default is `4`.
`page_width`	numerical. Width of page (in inches). Default is set to `8.5`.
`page_height`	numerical. Height of page (in inches). Default is set to `11`.
`width_margin`	numerical. The width margin of the page (in inches). Default is `0.25`.
`height_margin`	numerical. The height margin of the page (in inches). Default is `0.5`.
`x_space`	numerical. An integer between `190` - `250`. This sets the distance between the QR code and text of each label. Default is `215`.
`y_space`	numerical. An integer between 80 and 215. Default is 182.

Details

barcode_make is the helper function generating the actual QR code and creating the page layout for printed labels.
