I am trying to show the results summary using gWidgets, but I cannot find a widget that can do the job easily.
For example,
ctl <- c(4.17,5.58,5.18,6.11,4.50,4.61,5.17,4.53,5.33,5.14)
trt <- c(4.81,4.17,4.41,3.59,5.87,3.83,6.03,4.89,4.32,4.69)
group <- gl(2,10,20, labels=c("Ctl","Trt"))
weight <- c(ctl, trt)
lm.D9 <- lm(weight ~ group)
I would like to have a window or a text box which prints summary(lm.D9). like the following:
Call:
lm(formula = weight ~ group)
Residuals:
Min 1Q Median 3Q Max
-1.0710 -0.4938 0.0685 0.2462 1.3690
Coefficients:
Estimate Std. Error t value Pr(>|t|)
(Intercept) 5.0320 0.2202 22.850 9.55e-15 ***
groupTrt -0.3710 0.3114 -1.191 0.249
---
Signif. codes: 0 ‘***’ 0.001 ‘**’ 0.01 ‘*’ 0.05 ‘.’ 0.1 ‘ ’ 1
Residual standard error: 0.6964 on 18 degrees of freedom
Multiple R-squared: 0.07308, Adjusted R-squared: 0.02158
F-statistic: 1.419 on 1 and 18 DF, p-value: 0.249
This can be easily done with shiny using renderPrint and verbatimTextOutput. I am hoping that there is also something in gWidgets.
A related question, I can use capture.output to write the summary into a text file. It would be helpful if there is a widget that can open the text file and show the content in the user interface.
Use gtext and capture.output:
out <- paste(capture.output(summary(lm.D9)), collapse="\n")
w <- gwindow()
txt <- gtext(out, cont=w, font.attr=c(family="monospace"))
