Hi everybody, I would like to plot only a part of a data frame, and identify the IDs for all the points with values higher than a certain value. I will try to be more explicit:
I did a qqnorm plot of my data. It is obvious from the plot that all the sample quantiles which are in Theoretical Quantiles = or > than 1 belong to another group. To be sure about that I plot the cooks.distance for the same data, and sure enough the data with the indices grater than 250 (x axis) have obvious higher Cook �s distance than the majority of the data. The data indices on the Cook�s distance plot are different than my data ID (in my data table) which is �character type�. How do I identify the IDs of the data I am interested into, and how I can plot only the data with Theoretical Quantiles equal or grater than 1? And, of course, how can I plot only the Cook�s distance for the data with indices higher than a certain number, or Cook�s distance higher than a certain number???? And, on the same line, how can I sort a tab-delimited table after the values from one column? I know how to assign one column to a vector and sort that vector, but what if I want to sort the whole table, like in Excel for example?
