Wetland is a modern object-relational mapper (ORM) for node.js based on the JPA-spec. It strikes a balance between ease and structure, allowing you to get started quickly, without losing flexibility or features. New! Take a look at our wetland tutorial. New! Wetland CLI now has its own repository. npm i -g wetland-cli.

QUESTION
I'm trying to create a string formula with the independent variables that are significant within my linear model, though I'm finding it difficult trying to include the +
at the end of each variable.
I have tried:

QUESTION
I am wondering if there is a way to read in files from your directory without single quotes around them. My directory has several geodataframes with the same suffix. I can read them all in and append to a list but the list will contain single quotes around each DataFrame name, making it a str.
...ANSWER
Answered 2021-Mar-03 at 04:36I am pretty sure, what you are trying to achieve here, would have been really not necessary. But I would just answer what you ask and based on what I understand about your requirements.
As, you are trying to use the dataframe names in a loop structure I am assuming that the dataframes are available in the loop's scope.
which you have shown using dir()
command in your example.
From python docs:
dir(...)
dir([object]) -> list of stringsIf called without an argument, return the names in the current scope.
Now let's assume the list in which your DataFrame names are present is
QUESTION
I am working on a website and have it set to work full screen, but, I wanted to make it responsive. I used a grid and am not sure how this transfers over to responsive. I have the media tags on the bottom of the CSS page and the grid is in the first half of the HTML page. I would like to rearrange the CSS so that when the website is open on the phone that the title is at the top then the image shows up first then some of the article, then another image and then more article.
...ANSWER
Answered 2021-Mar-01 at 21:26You can basicaly redefine and reorder every grid element in a mediaquery after it. Just adjust the values to your liking
QUESTION
I have a dataframe of landcover types from year 2010 and 2019. Pland represent the total landcover value, 1 is equal to 100% of that particular area, relative to the id. These calculations are made beforehand, and id represent each geometry.
I want to perform a function that produces another column with these descriptive names, where the *
represents the name to be replaced:

QUESTION
I've read several posts about having convergence issues with glmer and I have tried a couple recommended work arounds (changing optimizer, changing model iterations, etc.) but nothing seems to resolve my convergence issue. I was wondering if someone could help me figure out what I am doing wrong?
Data description: The data is count data of Monarch butterfly stages throughout several years at different sites within the year. The data has over 6000 observations, but the number of observations and sites vary across years. The data has several zeros (no Monarch observed) and the data is over dispersed.
Count: Response variable of how many individuals were counted
Year: Factor with 6 levels
Stage: Factor with 7 levels
Site: Random categorical variable. Listed as a random variable because each site is a replicate within the year

...ANSWER
Answered 2021-Jan-07 at 00:38tl;dr I think your fit is actually fine. For negative binomial GLMMs I have now taken to recommending glmmTMB
rather than lme4::glmer.nb
. In any case, it works for checking the model parameters with a completely different implementation/algorithm for the model and making sure the answers are the same, which is the gold standard for addressing convergence warnings ...
QUESTION
I am performing a PLS-DA analysis in R using the mixOmics package. I have one binary Y variable (presence or absence of wetland) and 21 continuous predictor variables (X) with values ranging from 1 to 100.
I have made the model with the data_training
dataset and want to predict new outcomes with the data_validation
dataset. These datasets have exactly the same structure.
My code looks like:

Answered 2020-Dec-24 at 04:58Without reproducible there is no way to test this but you need to convert the code you want to run each time into a function. Something like this:

I've a situation where I'm trying to select some scenarios from a dataframe in a single pass. The following code is what I'm using at the moment:
...ANSWER
Answered 2020-Oct-23 at 01:24You should use &
instead of and
as well as wrap parentheses around each condition. Formatting on new lines with everything lining up also helps prevent mistakes with parentheses:
QUESTION
I am performing a splsda-model in R on 10 dataframes (data of 10 study areas), stored as a list (datalist
). All these dataframes are similar, with the same variables, but just different values.
I use the micromics library to do this.
This is the head of the first study area. It compares the absence or presence of wetlands (factor variable - wetl or no wetl) depending on its value of TPI of different ranges.
...ANSWER
Answered 2020-Aug-07 at 16:49Based on your outputs, you will have to create a new list and save the results on it. Using just myperf_plsda
could be overwriting each step in the loop. Also most of the measures you want are lists, so I added some processing functions to reach dataframes. I used next dummy data:

ANSWER
Answered 2020-Aug-04 at 16:38With the sample data you provided, here a solution to save in one pdf each of the plots. For the sake of making reproducible the exercise, I have created datalist
with the input you added. In your real problem you must have datalist
with names in order to add the titles to plots. Also some data for plots was not available like datastudyarea1
but it will not be difficult completing that part of the code for you. Here is the sketch:
QUESTION
I have a list of 10 dataframes, called "datalist", on which I want to apply several functions. I am quite new to R. I searched on the internet but can't find the right solution.
The dataframes all have the same variables, like simplified example below:
...ANSWER
Answered 2020-Jul-30 at 13:13You can write a custom model fitting function to subset the data.frames selecting just the columns of interest and run the modeling function.
