# Create a sample dataset for temperature, salinity, and pressure

  salinity = c(30, 32, 34, 36, 38),
  temperature = c(10, 15, 20, 25, 30),

# Convert the dataset to a ctd object
ctd_data <- as.ctd(salinity = data$salinity, 
                   temperature = data$temperature, 
                   pressure = data$pressure)

# Create a temperature-salinity diagram
plotTS(ctd_data, 
       xlab = "Salinity (PSU)", 
       ylab = "Temperature (°C)", 
       main = "Temperature-Salinity Diagram")
