I have a question:
I use JMP IN and GraphicalAnalysis for my Honors Chem. Projects. I would like to be pointed in the right direction: I would like to know how to use R to obtain the same data I would if I were to use JMP IN and GraphicalAnalysis.
I would need to be able to do the following:
produce a graphical depiction of :
Oneway ANOVA
Standard Deviation (Lines :JMPin)
Means(Diamonds, Dots :JMPin)
Data Points
Standard Error (Bars/Lines :JMPin)
I would have to be able to "Fit X by Y" and make the X-axis Proportional
I would need to obtain the following numerical data: <Summary of Fit> RSquare RSquare Adj Root Mean Square Error Mean of Response Observations (or Sum Wgts) <Analysis of Variance> Source DF Sum of Squares Mean Square F-Ratio Model Error C-Total <Means for Oneway ANOVA> Level Number Mean Std-Error <Means and Std Deviations> Level Number Mean Std-Dev Std-Err-Mean
I would also need to produce data that would illustrate my precision of measurements and my accuracy of measurements... Either Graphically or Numerically or both...
My class uses %CV to illustrate precision where %CV= (sd()/mean)*100
But any or all other methods used to calculate precision (and accuracy) would be fine too...
<The above was to describe a replacement for JMP IN>
For a replacement for GraphicalAnalysis, I would need the following information:
A graph that would have points depicting the data entered with a "Fit Line"
a "Curve Fit" that would be set for "Linear" a Linear Equation...
The "Liner Fit" would be depicted on the graph, the equation of the line in y = mx+b format, the m(slope) of the line, the b(Y-intercept) of the line, and the Correlation [coefficient] of the line...
I would have to be able to annotate the graph with my name, a title for the graph, the date, and the equation of the line...
I would also need to be able to print out the dataset used to create the graph...
also, I would need interpolative functionality: I would need to be able to figure out data while having only one known variable (ie.: we had to analyze the concentration of a pigment using a Spectrometer we had two variables: Concentration and Absorbance, several of the samples had "Unknown" concentrations while having known absorbances, we needed to find their Concentrations by interpolating the "Linear Fit For: Spectrometer Data" which entailed finding the spot where Absorbance (foo) hit the line, then we would assign the (bar) value (x axis value to y value) to Concentration, the Unknowns are now known!!!
Many Thanks In Advance to the Kind peoples whom helped me find, and understand the information I requested!!!
