# Intro
|
|
|
|
I try my best to share my basic workarounds in R to more effectively do statistical research. Feel free to be inspired or comment.
|
|
|
|
AS all functions have been collected in the package daDoctoR, please refer to the documentation there.
|
|
Install the package with the following command: devtools::install_github('agdamsbo/daDoctoR')
|
|

## Further research
|
|
|
|
In need of a suitable function to perform the chi-squared test of Hardy-Weinberg-equillibrium in my study poppulation, I ended up writing my own. It also contains a few summarise functions. This is actually the function I am most proud of, as it represents an actual universal test for both bi- and triallelic sustems in non-sexcromosome genes.

|
|
### Genotype distribution testing
|
|
- hwe_allele.R -- requires input in the form of two vectors with alleles listed
|
|
- hwe_geno.R -- requires input as numbers of each genotype (mm, mn, nn for biallelic systems and mm, mn, nn, mo, no, oo for triallelic)
|
|
- hwe.sum.R -- summarising tests for genotypes grouped by af factor. Performs HWE test for each group and returns neatly formatted distribution for easy copy-pasting to print. No comparisons of groups. Use the oddsratio or chisq.test.
|
|
|
|
### Formatting large data frames
|
|
- col_fact.R -- formatting columns as factor for names containing text elements of a vector provided. Labels or levels can be provided.
|
|
- col_num.R -- formatting columns as numeric for names containing text elements of a vector provided.
|
|
|
|
### Bivariate logistic regression analyses
|
|
- rep_glm.R -- for a stepwise gating regression approach this provides several bivariate logistic regression analyses for columns of a dataframe specified by af vector of the format c(). Use the dput() to obtain names of dataframe in correct format.
|
|
- rep_lm -- same as rep_glm, but for linear models
|
|
- rep_reg_cie.R -- Analysis of change in estimate approach with specified cut set at 10 % as standard.
|
|
|
|
### Publishin
|
|
- strobe_print.R -- regression analysis table complying with STROBE.
|
|

## Research year
|

|
|
Commands for extracting data from cpr-numbers:
|
|
- age_calc_function.R
|
|
- cpr_check_function.R
|
|
- cpr_sex_function.R
|
|
- date_convert_function.R
|
|
- dob_extract_cpr_function.R
|
|
|
|
All of these commands are written to work with the Danish Central Person Registry (CPR) numbers of the format ddmmyy-xxxx.
