ledger is an R package to import data from plain text accounting software like Ledger, HLedger, and Beancount into an R data frame for convenient analysis, plotting, and export.
Right now it supports reading in the register from ledger, hledger, and beancount files.
To install the last version released to CRAN use the following command in R:
install.packages("ledger")To install the development version of the ledger package (and its R package dependencies) use the install_github function from the remotes package in R:
install.packages("remotes")
remotes::install_github("trevorld/r-ledger")This package also has some system dependencies that need to be installed depending on which plaintext accounting files you wish to read to be able to read in:
ledger
ledger (>= 3.1)
hledger
hledger (>= 1.4)
beancount
beancount (>= 2.0)
To install hledger run the following in your shell:
stack update && stack install --resolver=lts-14.3 hledger-lib-1.15.2 hledger-1.15.2 hledger-web-1.15 hledger-ui-1.15 --verbosity=error To install beancount run the following in your shell:
pip3 install beancountSeveral pre-compiled Ledger binaries are available (often found in several open source repos).
To run the unit tests you’ll also need the suggested R package testthat.
The main function of this package is register which reads in the register of a plaintext accounting file. This package also registers S3 methods so one can use rio::import to read in a register, a net_worth convenience function, and a prune_coa convenience function.
register()Here are some examples of very basic files stored within the package:
library("ledger")
ledger_file <- system.file("extdata", "example.ledger", package = "ledger")
register(ledger_file)

df2 <- rio::import(bean_example_file)
all.equal(df, tibble::as_tibble(df2))
## [1] TRUEThe main advantage of this is that it allows one to use rio::convert to easily convert plaintext accounting files to several other file formats such as a csv file. Here is a shell example:
bean-example -o example.beancount
Rscript --default-packages=ledger,rio -e 'convert("example.beancount", "example.csv")'net_worth()Some examples of using the net_worth function using the example files from the register examples:

First we load the (mainly tidyverse) libraries we’ll be using and adjusting terminal output:
library("ledger")
library("dplyr")
filter <- dplyr::filter
library("ggplot2")
library("scales")
library("tidyr")
library("zoo")
filename <- tempfile(fileext = ".beancount")
system(paste("bean-example -o", filename), ignore.stderr=TRUE)
df <- register(filename) %>% mutate(yearmon = zoo::as.yearmon(date)) %>%
filter(commodity=="USD")
nw <- net_worth(filename)Then we’ll write some convenience functions we’ll use over and over again:
print_tibble_rows <- function(df) {
print(df, n=nrow(df))
}
count_beans <- function(df, filter_str = "", ...,
amount = "amount",
commodity="commodity",
cutoff=1e-3) {
commodity <- sym(commodity)
amount_var <- sym(amount)
filter(df, grepl(filter_str, account)) %>%
group_by(account, !!commodity, ...) %>%
summarize(!!amount := sum(!!amount_var), .groups = "drop") %>%
filter(abs(!!amount_var) > cutoff & !is.na(!!amount_var)) %>%
arrange(desc(abs(!!amount_var)))
}Here is some basic balance sheets (using the market value of our assets):
print_balance_sheet <- function(df) {
assets <- count_beans(df, "^Assets",
amount="market_value", commodity="mv_commodity")
print_tibble_rows(assets)
liabilities <- count_beans(df, "^Liabilities",
amount="market_value", commodity="mv_commodity")
print_tibble_rows(liabilities)
}
