prof.tree

Travis-CI Build Status Coverage Status CRAN Status

Provide an alternative profiling data diplay as tree structure.

Installation

To install the latest release version from CRAN with:

install.packages("prof.tree")

To install the development version the install_github() function from devtools package can be used:

devtools::install_github("artemklevtsov/prof.tree")

Example

times <- 4e5
cols <- 150
data <- as.data.frame(x = matrix(rnorm(times * cols, mean = 5), ncol = cols))
data <- cbind(id = paste0("g", seq_len(times)), data)
Rprof(tmp <- tempfile())
data1 <- data   # Store in another variable for this run
# Get column means
means <- apply(data1[, names(data1) != "id"], 2, mean)
# Subtract mean from each column
for (i in seq_along(means))
    data1[, names(data1) != "id"][, i] <- data1[, names(data1) != "id"][, i] - means[i]
Rprof(NULL)
library(prof.tree)
prof.tree(tmp)
unlink(tmp)
