This function is used to increment / decrease sequential scripts within the specified directory, allowing efficient adjustment of script sequence for additional or removed files.

Usage

adj_file_nos(target, directory = NULL, action = "up", step = 1)

Value

Renumbers filenames in the specified directory, according to the specified action. Only affects the target file and above.

Arguments

target

Required. The number in the sequential scripts to begin the adjustment. Use single digits only. The adjustment will affect script with that leading digit and greater.

The directory holding the sequential scripts.

Examples

.old_wd <- setwd(tempdir())

seq_file_ops(n = 10, target_dir = "munge")

# Increase files numbered 6 and above by 1
adj_file_nos(target = 6, directory = "munge")

# Increase above target files by a further 2
adj_file_nos(target = 6, directory = "munge", step = 2)

# Use step = "down" to restore original sequence
adj_file_nos(target = 6, directory = "munge", action = "down", step = 3)

# writing books or websites:
seq_file_ops(n = 5, target_dir = "images", filetype = "png")
# adjust by decimals
adj_file_nos(target = 1, directory = "images", step = 0.1)

# tidying up environment
unlink(c("munge", "images"), recursive = TRUE)
