Resolve Bug Causing Internal Errors with New Data Format (AYGU-1_MeltR)

[adhampton110]

Fixes 181

What was changed?

I revised the parsing logic in server.r to comply with MeltR's expected dataset format for files that have the same structure as AYGU-1_MeltR.

Why was it changed?

As stated in the user story, going forward, user input data will be structured like AYGU-1MeltR.csv. The current code strictly supports input files structured like test.csv. My code now supports input files structured like AYGU-1_MeltR.csv, instead of input file structured like test.csv.

How was it changed?

The new input file standard, AYGU-1MeltR.csv, already complies with MeltR, almost. I have added one line that manipulates the data before it interacts with MeltR: data <- raw_data %>% arrange(Sample). This line sorts the input data by the Sample column from lowest to highest (1,2,3,4,...).

Additionally the assignment of numSamples has been changed from NULL to 0. This was done because the following would occur:

9 + NULL = numeric(0). 
# problematic because we are unable to use the varaible later on to iterate during the creation of samples. 

Screenshots that show the changes (if applicable):

Each of the following cases were testing with the following configuration:

• AYGU-1MeltR.csv input file
• No Blank
• 260 Wavelength
• 90 Temp
• RNA NucAcid
• CGAAAGGU,ACCUUUCG Sequence
• Nucleic Acid Sequence Molar Extinction Coeff.
• Methods 2 & 3 Enabled
• nls Tm method
• Heteroduplex molecular state
