Plotting functions on top of datapoints in R -

-

Is it possible to overlay a mathematical function at the top of the data using ggplot? 

  ## Add gaglot2 library (ggplot2) # function eq = function (x) {x * x} # data x = (1:50) y = eq (x) # plot object P = qplot (x, y, xlab = "x-x", ylab = "y-axis",) # plot equation c = curve (eq) # data and function p + c # combine?

In this case my data is generated using the function, but I understand how to do curve () with ggplot.

You probably want: 

  library ("ggplot2") Eq & lt; - Function (x) {X * x} TMP & lt; - data.frame (x = 1: 50, y = eq (1:50)) Plot object P & lt; - qplot (x, y, data = tmp, xlab = "x-axis", ylab = "y-axis") C & lt; - stat_function (fun = eq) print (p + c)

and if you want to actually use the curve () , that is, calculated X and y coordinate: 

  qplot (x, y, data = as.data.frame (curve (eq)), geom = "line")
< / Div>

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
