bug: Error creating analytics files with prohibited characters in parameter names

[DitlevHB]

Hi Daptics,

I have completed a new campaign of 10 generations using Daptics API Version 0.9.3 and I get the following errors (1,2) when runnning "get_all_analytics_files" for session "06bf3gqzmiigwzab7io7":

(1)
failed with error: {'path': ['createAnalytics'], 'message': "In /home/shiny/rservex-sessions/Ditlev_20200412155004.wzn6.local/R , runtime error: Error in FUN(X[[i]], ...): object 'log_k' not found\n", 'locations': [{'line': 2, 'column': 0}]}

(2)
failed with error: {'path': ['createAnalytics'], 'message': 'In /home/shiny/rservex-sessions/Ditlev_20200413104912.uqok.local/R , runtime error: Error in pdf(fileName): too many open devices\n', 'locations': [{'line': 2, 'column': 0}]}

ESD parameter names are:
log_k+O1
log_k-O1
log_k+O2
log_k-O2
log_k+T
log_k-T
log_kL

Could the first error have something to do with the fact that parameter names contain hyphens or plus signs?

EDIT:
Certain special characters (-, +) are not allowed in ESD parameter names, and so I have successfully completed a new campaign after stripping hyphens and plus signs.

Best,
Ditlev

Possible solutions. Either forbid these names (which conflicts with ProtoLife/pdt-server#528), or use backticks to protect column names in plotting functions.
