ISAnalytics 1.4.3
In this vignette we’re going to explain in detail how to use functions of the aggregate family, namely:
aggregate_metadata()aggregate_values_by_key()ISAnalytics can be installed quickly in different ways:
devtoolsThere are always 2 versions of the package active:
RELEASE is the latest stable versionDEVEL is the development version, it is the most up-to-date version where
all new features are introducedRELEASE version:
if (!requireNamespace("BiocManager", quietly = TRUE))
install.packages("BiocManager")
BiocManager::install("ISAnalytics")DEVEL version:
if (!requireNamespace("BiocManager", quietly = TRUE))
install.packages("BiocManager")
# The following initializes usage of Bioc devel
BiocManager::install(version='devel')
BiocManager::install("ISAnalytics")RELEASE:
if (!require(devtools)) {
install.packages("devtools")
}
devtools::install_github("calabrialab/ISAnalytics",
ref = "RELEASE_3_14",
dependencies = TRUE,
build_vignettes = TRUE)DEVEL:
if (!require(devtools)) {
install.packages("devtools")
}
devtools::install_github("calabrialab/ISAnalytics",
ref = "master",
dependencies = TRUE,
build_vignettes = TRUE)ISAnalytics has a verbose option that allows some functions to print
additional information to the console while they’re executing.
To disable this feature do:
# DISABLE
options("ISAnalytics.verbose" = FALSE)
# ENABLE
options("ISAnalytics.verbose" = TRUE)
Some functions also produce report in a user-friendly HTML format, to set this feature:
# DISABLE HTML REPORTS
options("ISAnalytics.reports" = FALSE)
# ENABLE HTML REPORTS
options("ISAnalytics.reports" = TRUE)We refer to information contained in the association file as “metadata”:
sometimes it’s useful to obtain collective information based on a certain
group of variables we’re interested in. The function aggregate_metadata()
does just that: according to the grouping variables, meaning the names of
the columns in the association file to perform a group_by operation with,it
creates a summary. You can fully customize the summary by providing a
“function table” that tells the function which operation should be
applied to which column and what name to give to the output column.

#> 15 DNAnumber <formula> NA {.col}You can either provide purrr-style lambdas (as given in the example above),
or simply specify the name of the function and additional parameters as a
list in a separated column. If you choose to provide your own table you
should maintain the column names for the function to work properly.
For more details on this take a look at the function documentation

lambda must be a named list of either functions or purrr-style lambdas:
if you would like to specify additional parameters to the function
the second option is recommended.
The only important note on functions is that they should perform some kind of
aggregation on numeric values: this means in practical terms they need
to accept a vector of numeric/integer values as input and produce a
SINGLE value as output. Valid options for this purpose might be: sum, mean,
median, min, max and so on.agg2 <- aggregate_values_by_key(
x = integration_matrices,
association_file = association_file,
key = "SubjectID",
lambda = list(mean = ~ mean(.x, na.rm = TRUE)),

parameter needs to be set to .x, other parameters can be set as usual.
You can also use in lambda functions that produce data frames or lists.
In this case all variables from the produced data frame will be included
in the final data frame. For example:
agg3 <- aggregate_values_by_key(
x = integration_matrices,
association_file = association_file,
key = "SubjectID",
lambda = list(describe = ~ list(psych::describe(.x))),
value_cols = c("seqCount", "fragmentEstimate")
