This reproducible R Markdown analysis was created with workflowr (version 1.5.0). The Checks tab describes the reproducibility checks that were applied when the results were created. The Past versions tab lists the development history.
Great! Since the R Markdown file has been committed to the Git repository, you know the exact version of the code that produced these results.
Great job! The global environment was empty. Objects defined in the global environment can affect the analysis in your R Markdown file in unknown ways. For reproduciblity it’s best to always run the code in an empty environment.
The command set.seed(1) was run prior to running the code in the R Markdown file. Setting a seed ensures that any results that rely on randomness, e.g. subsampling or permutations, are reproducible.
Great job! Recording the operating system, R version, and package versions is critical for reproducibility.
Nice! There were no cached chunks for this analysis, so you can be confident that you successfully produced the results during this run.
Great job! Using relative paths to the files within your workflowr project makes it easier to run your code on other machines.
Great! You are using Git for version control. Tracking code development and connecting the code version to the results is critical for reproducibility. The version displayed above was the version of the Git repository at the time these results were generated.
Note that you need to be careful to ensure that all relevant files for the analysis have been committed to Git prior to generating the results (you can use wflow_publish or wflow_git_commit). workflowr only checks the R Markdown file, but you know if there are other scripts or data files that it depends on. Below is the status of the Git repository when the results were generated:

Here we create plots and tables to compare various methods, including SMASH, for reconstructing a spatially structured signal from Poisson-distributed data. Similar to the Gaussian simulations, we generated data sets using a variety of test functions and intensity ranges. Specifically, we considered 6 test functions, rescaling the test function so that the smallest intensity was \(x\) and the largest intensity was \(y\), with \((x,y)\) set to either \((1/100, 3)\), \((1/8, 8)\) or \((1/128, 128)\).
For each combination of test function and intensity range, we simulated 100 data sets. In the plots and tables below, we summarize the error (MISE) in the estimates computed in the 100 data sets from each simulation setting.
The plots shown below for the “Bursts” simulations were included in the manuscript.
Analysis settings
We will extract the results from these methods:
methods <- c("ash","BMSM","haarfisz_R")These variables specify the row and column names for the tables:
table.row.names <- c("SMASH","BMSM","Haar-Fisz")
table.col.names <- c("(1/100,3)","(1/8,8)","(1/128,128)")These are settings used in plotting the test functions:
n <- 1024
t <- 1:n/nSet up environment
Load the knitr, kableExtra, ggplot2 and cowplot packages.
library(knitr)
library(kableExtra)
library(ggplot2)
library(cowplot)
library(xtable)Some of the test functions are defined in signals.R, so we load them here:
source("../code/signals.R")Load results
Load the results of the simulation experiments.
load("../output/pois.RData")Spikes data
This is the function used to simulate the “Spikes” data sets at different ranges of intensities:
mu.s <- spike.f(t)
plot(t,mu.s,xlab = "",ylab = "",type = "l",lwd = 2,col = "darkorange")

Clipped Blocks data
This is the function used to simulate the “Clipped Blocks” data sets at different ranges of intensities:
pos <- c(0.1,0.13,0.15,0.23,0.25,0.4,0.44,0.65,0.76,0.78,0.81)
hgt <- 2.88/5 * c(4,-5,3,-4,5,-4.2,2.1,4.3,-3.1,2.1,-4.2)
mu.cb <- rep(0,n)
for (j in 1:length(pos))
mu.cb <- mu.cb + (1 + sign(t - pos[j])) * (hgt[j]/2)
mu.cb[mu.cb < 0] <- 0
plot(t,mu.cb,xlab = "",ylab = "",type = "l",lwd = 2,col = "darkorange")
