plot_spectraNMR {MWASTools} | R Documentation

## Plot NMR spectra

### Description

This function generates an NMR spectra plot, with the chemical shifts displayed along the x-axis, and the peak intensities displayed on the y-axis.

### Usage

    plot_spectraNMR (metabo_SE, type = "l", lty = 1, xlab ="ppm",
                     ylab ="intensity", xlim = NULL, ...)

### Arguments

`metabo_SE` | SummarizedExperiment object. See "MWAS_SummarizedExperiment()".
`type` | character vector indicating the type of plot for each row of metabo_matrix. For all possible types, see "plot()".
`lty` | character vector of line types. For all possible types, see "plot()".
`xlab` | character vector specifying a title for the x-axis.
`ylab` | character vector specifying a title for the y-axis.
`xlim` | numeric vector containing the minimum and maximum values of the x axis. Notice that ppm is displayed in reverse scale (e.g. xlim = c(10, 0)).
`...` | other arguments passed to "matplot()".

### Value

An NMR spectra plot.

### Examples

    ## Load data
    data(metabo_SE)

    ## Plot first 2 spectra
    plot_spectraNMR (metabo_SE[, 1:2])
    plot_spectraNMR (metabo_SE[, 1:2], xlim = c(1.03, 0.85), main = "NMR spectra")
