问题 I am trying to open a dialog box that prompts the user to select a file and then using that file in a function written for a matlab toolbox called EEGLAB. The code is as follows: [F,PathName,FilterIndex] = uigetfile({'*.*','All Files(*.*)'}, 'Select your File ') b = strcat(PathName,F) Input = importdata(b) FF = Input.filename; %Loading the dataset into EEG lab. and rereferencing to Cz. EEG = pop_loadset('filename','FF','filepath','/Users/maheensiddiqui/Desktop/eeglab13_4_4b/EEG_data/Data

问题 Can ggplot2 be used to produce a so-called topoplot (often used in neuroscience)? Sample data: label x y signal 1 R3 0.64924459 0.91228430 2.0261520 2 R4 0.78789621 0.78234410 1.7880972 3 R5 0.93169511 0.72980685 0.9170998 4 R6 0.48406513 0.82383895 3.1933129 Full sample data. Rows represent individual electrodes. Columns x and y represent the projection into 2D space and the column signal is essentially the z-axis representing voltage measured at a given electrode. stat_contour doesn't work,

Rows represent individual electrodes. Columns x and y represent the projection into 2D space and the column signal is essentially the z-axis representing voltage measured at a given electrode. stat_contour doesn't work, apparently due to unequal grid. geom_density_2d only provides a density estimation of x and y . geom
