    Make multiple plots in one graph in R

    Thank you! Why is my values being considered as 'characters' inside R? I want to plot with ggplot but it wont work because they are not numerical.

    Plot and calculate value for y and x where functions intersect

    Hi everyone I have made this graph (attached). I want to calculate and plot a longitudinal line from the x-axis where the three functions meet first time at same value. How is it possible? Thanks!

    Make multiple plots in one graph in R

    Hi I have a data-file in excel as you can se in the picture :) I have tried several codes to plot a graph with the time on x-axis and the temperature on the y-axis for mesh0-mesh5. 1.How is it possible inside R? 2. Is it fine to use excel format or should it be csv?

    Enough to use RMSD to decide significance?

    Thanks anyway :)

    Seperate one column into two

    Hi As you can see I had a excel file that I loaded into R. The problem is that in the original file Time and Ave was seperated by comma and not by columns. When I load it in to R the commas that seperates them do not appear. How can I seperate these two columns? Now this column is for...

    RMSD stands for root-mean-squared-deviation :)

    Enough to use RMSD to decide significance?

    Hi I have calculated RMSD for two different simulation to decide how large the error/standard deviation is. How can I decide if the RMSD-value is small enough to show that there is no significant difference between the simulations? thanks

    the use of RMSD and NRMSD

    Hi everyone I have simulated the velocity in an object using fluid dynamics in transiet mode using different mesh-sizes. When the mesh-size is increased the accuracy of the simulation will increase. However, to a point there will be mesh independency, but the simulation variables (e.g. velocity...

    Repeated measure and blocking together

    Hi I am considering using a batch for each unit of 4 runs of total 16 runs, therefor I will have a total of 4 different batches (blocks). This to account for the variations found in different batches. I want to do it as it will be expensive to use 16 different batches. I also want to repeat the...

    Repeated measures, samples and control groupe

    Hi all Right I am struggling with understanding the concept behind some statistic when I deal with this problem; I have an experiment where I want to understand how long it take a fluid to reach a specific temperatur and how it effects its nutritional content when during a heating process. So...

    Experimental Design

    I only have n= 2 in this design so I should actually consider increasing it?

    Experimental Design

    That make sense! Thank you. I have another question :) I choose that the factor A is fixed as the material will origin from only 3 different composition (A1,A2,A3), B will also be fixed as I will only investigate three thicknesses of each material and also the machine will be fixed. However...

    Experimental Design

    I want to investigate the effect of material 1 on all levels of thickness and machine before the treatment and after and the same for material 2 and material 3. So it is only the material that change, but the other factors will be inside each level of material and this will be repeated 2 times...

    Experimental Design

    I want to investigate if some of these factors (A,B,C) can optimize the warming process in terms of time and nutritional content of some food when using different material of a container A (material1, material2, material3), different thickness of container B (thickness1, thickness2) and...

    Experimental Design

    Hi everyone I am trying to figure out the best possible way to design an experiment I am interested in. I want to investigate the effect of three factors (A,B,C) and A has 3-levels, B has 2-level and C has 2-level and we will have 2 runs. I want to investigate these factors before a treatment...

    Evalution of recored temperatures before and after

    The heating period depends on the amount of volume in each bottle. We had 8 bottles with different sizes and volumes of fluid :) Temperature before <-- x(32, 36, 41, 42, 37, 37, 38, 37) Temperature after <-- x(32, 33, 35, 41, 38, 33, 37, 35)

    Evalution of recored temperatures before and after

    Thank you very much! but why can I not use paired t-test? I know that due to the small sample size it is difficult to assume whether the data is normal or non-normal distributed. So of course based on this, we can do a non-paramatic test, but is this the case every time we have a small sample size?

    Evalution of recored temperatures before and after

    Hi I have recorded the temperature of a fluid in a container before and after heating, and want to evaluate the significance by looking at the mean differences of the temperature before and after using SAS jmp. I used 8 different samples and from them I recorded the temperature before and...
