I am having hard time tabulating data in a dataframe, and getting a single "table" for an answer. I am trying to tabulate all "counts" for given "status" on a given date. I have a data frame such as: delta_ts status count 1 2008-02-27 CLOSED 3 2 2008-02-27 NEW 56 3 2008-02-27 RESOLVED 5 4 2008-02-21 ASSIGNED 1 5 2008-02-21 ASSIGNED 1 6 2008-02-21 NEW 2 7 2008-02-21 RESOLVED 0 8 2008-02-22 ASSIGNED 0 9 2008-02-22 CLOSED 0 10 2008-02...

Hello, I would like use Kalman filter for estimating parameters of a stochastic model. I have developed the state space model but I don’t know the correct way use Kalman filter for parameter estimation. Has anybody experience in work with Kalman filter in R. I don’t know the correct function. Maybe it is - KalmanLike; but what is the correct Input? - tsmooth? -

...port such a file to R and do some simple stuff (say plot the values)? As per the tutorials on time series, I could use the ts() method to import the values (not timestamps). However, one problem with my data is that the *time intervals are not regular* -- i.e. I don't have observations at every delta_t. So, I possibly can't ignore the timestamps. I'm also interested to estimate the Hurst exponent for the above series. I've installed the fArma package. Again, I'm not sure how to use the above series there. Could someone please help me on this? -- Thanks, Barun Saha JPA IIT, Kha...

Hello, I don't understand the description / help-text for the numericDeriv() function. Why is there a new environment used? And what is meant with an environment here? Is it similar or the same as a local workspace, like an environment in functional languages? And why is it needed here? numericDeriv could just calculate the difference bewtween two values and divide this difference by the

The real sudo does it as well, and leaving them when preserving the environment (-E) maybe breaks the applications, as e.g. chroot will have a TMPDIR path pointing outside of it. --- dib/dib.ml | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/dib/dib.ml b/dib/dib.ml index df83ba1..d15cd19 100644 --- a/dib/dib.ml +++ b/dib/dib.ml @@ -301,6 +301,11 @@ if [ -z \"$preserve_env\" ];
