Individual Commit Timestamps (from git repositories)
Description
Every commit from FreeBSD, OpenBSD, NetBSD, and PostgreSQL with full timestamps and anonymized author IDs. Extracted from cloned git repositories.
Usage
data(oss_commits)Format
A data frame with 2068717 rows and 3 variables:
- project
character, project name
- timestamp
POSIXct, commit timestamp in UTC
- author_id
character, anonymized 12-character author hash
Source
Cloned from https://github.com/freebsd/freebsd-src, https://github.com/openbsd/src, https://github.com/NetBSD/src, https://github.com/postgres/postgres
Examples
data(oss_commits)
fb <- oss_commits[oss_commits$project == "freebsd", ]
hours <- as.POSIXlt(fb$timestamp)$hour
hist(hours, breaks = 0:24, main = "FreeBSD Commits by Hour of Day",
xlab = "Hour (UTC)", col = "steelblue")
Open Source Project Contributor Signups (Monthly)
Description
Monthly new contributor signup counts for open source projects. No personal information included.
FreeBSD data represents Phabricator account registrations. Other projects approximate signup date as the date of each author's first commit on GitHub (top 100 contributors).
Note: signups and commit activity are different metrics.
Usage
data(oss_contributors)Format
A data frame with 447 rows and 5 variables:
- project
character, project name
- source
character, data source (phabricator or github)
- month
Date, first day of each month
- new_contributors
integer, new contributors that month
- cumulative
integer, running total for that project
Source
FreeBSD: https://reviews.freebsd.org
GitHub: https://github.com/freebsd/freebsd-src, https://github.com/openbsd/src, https://github.com/NetBSD/src, https://github.com/postgres/postgres
Examples
data(oss_contributors)
projects <- split(oss_contributors, oss_contributors$project)
plot(NULL, xlim = range(oss_contributors$month),
ylim = c(0, max(oss_contributors$cumulative)),
xlab = "Date", ylab = "Total Contributors",
main = "Open Source Contributor Signups")
cols <- c(freebsd = "red", openbsd = "orange",
netbsd = "blue", postgresql = "purple")
for (p in names(projects)) {
d <- projects[[p]]
lines(d$month, d$cumulative, col = cols[p], lwd = 2)
}
legend("topleft", names(cols), col = cols, lwd = 2)
Open Source Project Contributor Signups (Daily, FreeBSD only)
Description
Daily signup counts for the FreeBSD Phabricator code review platform. Represents account registrations, not commit activity. Suitable for time series analysis. No personal information included.
Usage
data(oss_contributors_daily)Format
A data frame with 2531 rows and 5 variables:
- project
character, always "freebsd"
- source
character, always "phabricator"
- date
Date, the signup date
- new_contributors
integer, new signups that day
- cumulative
integer, running total
Source
Aggregated from public Phabricator user data at https://reviews.freebsd.org
Examples
data(oss_contributors_daily)

oss_contributors_daily$new_contributors,
type = "h", xlab = "Date", ylab = "New Signups",
main = "FreeBSD Daily Phabricator Signups")
Daily New Committers (from git repositories)
Description
Daily counts of authors making their first commit to each project. Extracted from cloned git repositories. Includes all authors.
Usage
