1. ### Make multiple plots in one graph in R

Thank you! I figured it out and solved the problem :)
2. ### 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.
3. ### Make multiple plots in one graph in R

I have tried this code but it wont work
4. ### 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!
5. ### 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?
6. ### Enough to use RMSD to decide significance?

Thanks anyway :)
7. ### 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...
8. ### Enough to use RMSD to decide significance?

RMSD stands for root-mean-squared-deviation :)
9. ### 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
10. ### 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...
11. ### 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...
12. ### 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...
13. ### Experimental Design

I only have n= 2 in this design so I should actually consider increasing it?
14. ### 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...
15. ### 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...
