removeFromList: Remove elements from a list file.

Description

Remove elements from a list file.

Usage

removeFromList(file, index)

Arguments

file

Name of file.

index

A numeric, logical or character vector.

Value

invisible TRUE if no error occurs.

Details

It removes elements with given indices or names. This function may relocate all the data in the stored file, thus can be very slow! Please consider to call this function batchwise instead of one index by one index. When it takes long time to process, some verbose info will be printed to console, which can be switched off by setting options(list(largeList.report.progress = FALSE)).

Examples

Run this code

list_1 <- list("A" = c(1,2), "B" = "abc", list(1, 2, 3))
saveList(object = list_1, file = "example.llo")

# by numeric indices
removeFromList(file = "example.llo", index = c(2))

# by name
removeFromList(file = "example.llo", index = c("A"))

# by logical indices
removeFromList(file = "example.llo", index = c(TRUE))
