27.14 Function Call Layout
Don’t add spaces around for named arguments in parameter lists. Visually this ties the named arguments together and highlights this as a parameter list. This style is at odds with the default R printing style and is the only situation where I tightly couple a binary operator. In all other situations there should be a space around the operator.
::read_csv(file="data.csv", skip=1e5, progress=FALSE)readr
read_csv(file = "data.csv", skip = 1e5, progress = FALSE)
For long parameter lists improve readability using a table format aligning on the .
::read_csv(file = "data.csv", readrskip = 1e5, progress = FALSE)
All but the final argument to a function call can be easily commented out. However, the latter arguments are often optional and whilst exploring them we will likely comment them out. An alternative puts the comma at the beginning of the line to easily comment out specific arguments except for the first one, which is usually more important and often non-optional. This is common amongst SQL programmers and can be useful for R.
dialPlot(value = 78, label = "UseR!", label_cex = 3, label_color = "black")
dialPlot(value = 78 label = "UseR!" , label_cex = 3 , label_color = "black" , )
dialPlot( value=78, label="UseR!", label_cex=3, label_color="black")
