Source: R/class_constructor.R
join_rowData.Rd

Join a new data frame of information to feature data of a SummarizedExperiment object. The data frame needs to have a column "Feature_ID". This function is usually used internally by some of the functions in the package, but can be useful.

Usage

join_rowData(object, dframe)

# S4 method for class 'SummarizedExperiment,data.frame'
join_rowData(object, dframe)

Arguments

object

a SummarizedExperiment

dframe

a data frame with the new information

Value

A SummarizedExperiment object with the new information added to rowData(object).

Examples

data(example_set)
new_info <- data.frame(
  Feature_ID = rownames(example_set),
  Feature_number = seq_len(nrow(example_set))
)
with_new_info <- join_rowData(example_set, new_info)
colnames(rowData(with_new_info))
#> [1] "Feature_ID"     "Split"          "Alignment"      "Average_Mz"    
#> [5] "Average_Rt_min" "Column"         "Ion_mode"       "Flag"          
#> [9] "Feature_number"
