ANSWER

Answered 2021-May-21 at 19:26

Flowtest1 isn't a dataframe, just a list of two vectors, so you can't use bracket notation to subset both vectors at once. Also, dates_FF is created with two arguments instead of a vector, so it doesn't work. as.Date is vectorized, so if you just make the two input dates a vector it will work. This returns what you want with no need for Flowtest1

How to use Trycatch to skip errors in data downloading in R

Answer

You wrote the tryCatch outside of getstreamflow. Hence, if one site fails, then getstreamflow will return an error and nothing else. You should either supply 1 site at a time, or put the tryCatch inside getstreamflow.

This seems really simple, yet I can't find an easy solution. I'm working with future streamflow projections for every day of a 25 year period (2024-2050). I'm only interested in streamflow during the 61 day period between 11th of April and 10th of June each year. I want to extract the data from the seq and Data column that are within this period for each year and have it in a data frame together.

I’m analyzing river streamflow data with R language and I have two nested lists. First holds data (Flowtest) from different river reaches called numbers such as 910, 950, 1012 and 1087. I have hundreds of daily streamflow measurements (Flow), but as I’m preparing yearly statistics the exact day and month doesn’t matter. Each measurement (Flow) is referenced to a year (Year) in the Flowtest table.

Get sum of row differences with Pandas .diff()

Asked 2020-Oct-26 at 03:52

I am doing a time-series analysis where I need to calculate the change in several attributes over time. Pandas makes a simple version of this easy; the .diff(periods=n) function will calculate the difference between a row and the preceding n rows, however, that is not quite what I need...

ANSWER

Answered 2020-Oct-26 at 03:52

sum of the single day differences over a span of n days

First, diff consecutive rows then do a rolling sum. Since the series after diff already has difference for 2 consecutive rows, for rolling sum we only provide period-1 (in our case 3-1 = 2).
