Examples

## Example 1

# Open the fluorescence eem
file <- system.file("extdata/cary/eem/", "sample1.csv", package = "eemR")
eem <- eem_read(file)

plot(eem)

# Open the blank eem
file <- system.file("extdata/cary/", "nano.csv", package = "eemR")
blank <- eem_read(file)

plot(blank)

# Remove the blank
eem <- eem_remove_blank(eem, blank)

plot(eem)

## Example 2

# Open the fluorescence eem
folder <- system.file("extdata/cary/eem/", package = "eemR")
eem <- eem_read(folder)

plot(eem, which = 3)

file <- system.file("extdata/cary/", "nano.csv", package = "eemR")
blank <- eem_read(file)
