[R] [R-pkgs] r2rtf: Easily Create Production-Ready Rich Text Format (RTF) Table and Figure

2021-06-01 Thread Yilong Zhang
Dear all,



I am happy to announce that {r2rtf} v0.3.0 is now on CRAN.



r2rtf is an R package to create production-ready tables and figures in RTF
format. The R package is designed to provide simple “verb” functions that
correspond to each component of a table or figure.



I hope you find it helpful. Please feel free to reach out with feedback or
questions.



CRAN: https://cloud.r-project.org/web/packages/r2rtf/index.html

Documentation: https://merck.github.io/r2rtf/articles/index.html



Thanks,



Yilong

[R] transfer string to expression

2010-10-31 Thread Yilong Zhang
Dear all:

when I use parse() there is some problems. Below is an example:

b0-1
b1-1
x-1
str2expr-function(x){eval(parse(text=x))}
test1-b0+b1*sqrt(x)
test2-b0+b1
str2expr(test1)
str2expr(test2)

it can work well for test2 but not for test1.

Could you tell me how to fix this problem or is there other more stable
method to transfer an string to expression?

best regards

Elong
