installed.packages(lib.loc = NULL, priority = NULL)
lib.loc |
character vector describing the location of R library trees to search through. |
priority |
character vector or NULL (default). If non-null, used to
select packages; "high" is equivalent to
c("base","recommended"). To select all packages without an
assigned priority use priority = "NA".

installed.packages scans the ‘DESCRIPTION’ files of each
package found along lib.loc and returns a matrix of package
names, library paths and version numbers.
A matrix with one row per package, row names the package names and
column names "Package", "LibPath", "Version",
"Priority", "Bundle", "Depends" and "Suggests".
str(ip <- installed.packages(priority = "high")) ip[, c(1,3:5)]
