Imports data from a user-supplied file, and converts it to a Daily data frame, appropriate for WRTDS calculations. The file can use most any separators as a delimiter. The default is comma separated.
The first column is expected to be dates, the second column is expected to be discharge values. If the date format is not automatically detected, the format can be specified using the "format" argument.
readUserDaily(filePath, fileName, hasHeader = TRUE, separator = ",",
qUnit = 1, format = "%m/%d/%Y", verbose = TRUE)A data frame 'Daily' with the following columns:

| Julian | integer | Number of days since Jan. 1, 1850 |
| Month | integer | Month of the year [1-12] |
| Day | integer | Day of the year [1-366] |
| DecYear | numeric | Decimal year |
| MonthSeq | integer | Number of months since January 1, 1850 |
| Qualifier | character | Qualifying code |
| i | integer | Index of days, starting with 1 |
| LogQ | numeric | Natural logarithm of Q |
| Q7 | numeric | 7 day running average of Q |

logical true if the first row of data is the column headers
character character that separates data cells. The default is "," for a csv file. Tab delimited would be "\t".
number 1 is cubic feet per second, 2 is cubic meters per second, 3 is 10^3 cubic feet per second, and 4 is 10^3 cubic meters per second. The default is 1.
character indicating the format of the date (which should

for options. The code will initially look for R's standard YYYY-MM-DD, and
check this format as a backup.
