Hola lista, tengo una base de datos muy grande de un datalogger. Consiste en un vector con 0's y 1's, y tengo que ver cuando hay 600 o más unos seguidos. Se me ocurrió hacerlo con un loop for. Pero tarda demasiado. También intente usar which para que seleccione solo los 1 para empezar a sumar pero no hay gran diferencia. A alguien se le ocurre alguna so...

Hi, I'm newish to R, a recent convert from Matlab... So far I'm impressed, and determined to solve the following problem, which seems like it should be easy: I have a long (millions of points) data series recorded with a datalogger that produced a timestamp in 4 columns: Year, Day of Year, Time in (H)HMM and Seconds. I would like to have R interpret these columns as a time object and have made some progress (e.g., using paste() to create a single column and then strptime() to interpret -- is that too roundabout??), but one t...

...lotting needs. I have been using lattice and Hmisc for most plots so far successfully, but I need help creating a plot I desire for some new data I have. This data frame consists of the same type of measurement (Eh) for 27 different locations. I have 8000+ measurements for each location, and my datalogger organizes the output like this: Date A1L A2L A3L 2005-07-14 22:00 208.1 -178.5 196.8 2005-07-14 22:10 207.9 -184.3 200.0 Now I'm having trouble plotting A1L, A2L, A3L on the same plot as a function of Date. I thought I would try panel.linejoin, like so: xyplot(data=redox2, A1...

I'm trying to get HOBOware Pro (http://www.onsetcomp.com/products/software/), a tool that interfaces with a USB based datalogger, to work under Wine. I have installed it, and it fails with the message: Code: Error occurred during initialization of VM Could not reserve enough space for object heap This seems to be fairly common among Java apps, and the solution appears to be setting -Xms & -Xmx parameters when calli...

Hello everyone ... Before I give up and install windows on my HD as well :-) Maybe there is a solution. The program to read the sampled data in the data-logger can be installed and started using WINE without problems. But the driver (which is installed separately) which allows the Data-logger to be recognised by the program on the USB port, cannot be installed. Its name is "Silicon
