kandi X-RAY | plant Summary
The plant package for R is an extensible framework for modelling size- and trait-structured demography, ecology and evolution in simulated forests. At its core, plant is an individual-based model where plant physiology and demography are mediated by traits. Individual plants from multiple species can be grown in isolation, in patches of competing plants or in metapopulations under a disturbance regime. These dynamics can be integrated into metapopulation-level estimates of invasion fitness and vegetation structure. Accessed from R, the core routines in plant are written in C++. The package provides for alternative physiology models and for capturing trade-offs among parameters. A detailed test suite is provided to ensure correct behaviour of the code.

QUESTION
I have a dataset that was recorded by observation(each observation has its own row of data). I am looking to combine/condense these rows by the plant they were found on - currently a character variable. All other columns are numerical vales.
EX:
This is the raw data |Sci_Name|Honeybee_count|Other_bee_Obsevrved|Stem_count| |---|---|---|---| |Zizia aurea|1|5|10| |Asclepias viridiflora|15|1|3| |Viola unknown|0|0|4| |Zizia aurea|0|2|6| |Zizia aurea|3|6|3| |Asclepias viridiflora|8|2|17|
and I want:
Sci_Name Honeybee_count Other_bee_Obsevrved Stem_count Zizia aurea 4 13 19 Asclepias viridiflora 23 3 20 Viola unknown 0 0 4I am currently pulling this data from a CSV already in table form. I have been attempting to create a new table/data frame with one entry of each plant species, and blanks/0s for each other variable, which I can then use to c-binding the two together. This, however, has been clunky at best and I am having trouble figuring out how to have each row check itself. I am open to any approach, let me know what you think!
Thanks :D

for denoting the rest of the variables. Specify the FUN
as sum

QUESTION
I have question concerning easyadmin3. In my admin panel I have a productCrudController and one of the values I want to be able to set when creating a new product is the price. For the price I have a separate table though which contains all my prices with a date. The idea being that the price of a product van change over time and my client wants to be able to have an overview of the price history for each product.
So in my productCrudController I work with an associationField to link to my prices entity. However I'm really stuck with the following practical issue: I don't want to have to add a price in a priceCrudController which I would then be able to select in my productCrudController (the way the associationField expects me to do).
What I want is that I can create a product and input a price which would then be inserted into my prices table.
My code:
productCrudController ->
Right now I have a field for prices where I can select a price in a dropdown menu, but so I have to add the price first with a priceCrudController, which really isn't practical.

Install plant
You must be using R 4.1.0 or newer. At this stage the package is not on CRAN. You're options for installing are described below.
Installation requires a C++11 compatible C compiler (OSX >= 10.10/Yosemite satisfies this, as do standard linux Ubuntu 12.04 and 14.04). On Windows machines you will need to install Rtools. When I tried this in Rstudio, the program automagically sensed the absence of a compiler and asked if I wanted to install Rtools. Click Yes!
