Create a boxplot with an ExpressionSet object
Now that you've combined all the experimental data into one ExpressionSet object, it is more convenient to subset the features and samples. In this exercise, you'll once again create a boxplot to visualize one gene, but this time also subset the samples that are included in the plot.

Differential Expression Analysis with limma in R
Anleitung zur Übung
The ExpressionSet eset
has been loaded in your workspace.
Subset
eset
to only the first 10 samples (columns).Create a boxplot of the 1000th gene (i.e. row) in
eset_sub
using the accessor functionsexprs
,pData
, andfData
.

# Subset to only include the first 10 samples (columns)
eset_sub <- eset[___]
# Check the dimensions of the subset
dim(eset_sub)
# Create a boxplot of the 1000th gene in eset_sub
boxplot(___(eset_sub)[___, ] ~ ___(eset_sub)[, "Disease"],
main = ___(eset_sub)[___, "symbol"])
