Usually in agronomic studies, there exists the necessity of how the germination process of certain plant or variety works. It usually involves consecutives evaluations in time of a germination variable. Flavio et. al (2019) provides a germination study that includes germination evaluations that we are going to mimic to recreate an entire example of how an rfbapp
along with Field Book App
, a mobile phone application, can integrate each other to collect data into the field.
In aforementioned study, there is one variable named D
, which denote the number of germinated seeds in a certain day. For example: D1
number of germination seeds at day 1
. The study especify the number of seeds initially planted are 50 per experimental unit (EU). Thus, the researcher should count how many seed successfully germinated in a certain day from the initial sample of 50 seeds. For example: in day 1, the number of germinated seeds are D1=39
in first EU.
To create a variable list in `rfbapp`` that satisfy the aim of our study, we identify the followig attributes:
quantitative
0
50
D
10
In rfbapp
we can create quantitative variables as follows:
vars <- create_fbapp_template(variable = "D", type = "numeric", details = "Numer of germinated seeds", ntime = 10) vars
Now we export these set of variables via:
rfbapp::write_rfbapp(vars,file = "germination_variables.trt")
