I have a nested list with dates and river streamflow data (Flow) in different river reaches (910, 950, 1012, 1087):
...ANSWER
Answered 2021-May-21 at 19:26Flowtest1
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

I am trying to run a function to download data from the USGS website using dataRetrieval
package of R and a function I have created called getstreamflow
. The code is the following:
ANSWER
Answered 2021-May-17 at 20:34Based on the image showed in the new data, each element in the list
is nested as a list. We can extract the list
element (of length 1) with [[1]]
and then apply the Filter

I am trying to download data from the USGS website using the dataRetrieval
package of R.
For that purpose, I have generated a function called getstreamflow
in R that works fine when I ran for example.

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
.

I’m analyzing river streamflow data with R language and I have a list of data frames. Each data frame represents a subbasin (910, 950, 1012 and 1087) and has the exact same structure and number of variables and contains a value of IHA indicators (IHA1, IHA2) per Year (2004:2007)

QUESTION
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.

elements of 'seq_x' and select
the column
QUESTION
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.

QUESTION
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 03:52sum 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
).
