# FSS
Some useful functions for working with (German) farm structure survey
(FSS) data.
You can install the GitLab version of FSS from
[GitLab](https://git-dmz.thuenen.de/mindstep/fss) with:
devtools::install_git("https://git-dmz.thuenen.de/mindstep/fss")
Then the Related R packages can be installed.
library(FSS)
# Example
A little example for one specific function from the FSS package.
## Test a function
Here we will test one of the provided functions:
`generateFakeFSSData_DE()`. We generate some basic variables, which are
automatically produced. We set an additional variable to be generated,
namely C0300. The variable will be a continuous variable.
FSS_data_DE <- generateFakeFSSData_DE(C0codes = "C0300")
##
## Build fake data
### Add a specific categorical variable
No we will add a specific variable, i.e. a categorical variable if a
farm is an organic farm. This will be randomly distributed. The
probability of a farm to be organic is 20%.
library(tidyverse)
FSS_data_DE <- FSS_data_DE %>%
mutate(C0501=sample(c(0,1),
size = nrow(FSS_data_DE),
replace = TRUE,
prob = c(0.8,0.2)))
### Some analysis
After that we analyse the data regarding the number of farms that are
organic (C0501) for each year (C0008U1) and farm type (C0060UG1).
FSS_data_DE %>% group_by(C0008U1,C0060UG1,C0501) %>%
count() %>%
pivot_wider(names_from = C0060UG1, values_from = n) %>%
knitr::kable()
