Facing Error with command multiplot from coefplot package in R -

-

is there facing same when running command multiplot rpackage coefplot?

even example: 

data(diamonds) model1 <- lm(price ~ carat + cut, data=diamonds) model2 <- lm(price ~ carat + cut + color, data=diamonds) model3 <- lm(price ~ carat + color, data=diamonds) multiplot(model1, model2, model3)

i´m getting below error: 

error in get(x, envir = this, inherits = inh)(this, ...) :  attempt apply non-function

any hint?

this answer bit tangential, have found more recent combination of broom , dotwhisker packages useful - broom end (converting models "tidy" data frames of coefficients) , dotwhisker front end (creating plots via thin ggplot2 layer)

library(ggplot2) library(dotwhisker) library(broom)

update: re-installed dotwhisker v 0.2.0.3, appears work:

dwplot(list(model1,model2,model3))

you can dwplot(list(m1=model1,m2=model2,m3=model3)) if want pick different model names on fly.

alternatively, finer control can construct full data frame yourself:

mlist <- list(carat_cut=model1, carat_cut_color=model2,               carat_color=model3) library(plyr) ## extract tidy data frames , combine them ... mframe <- ldply(mlist,tidy,conf.int=true,.id="model")

now can do

dwplot(mframe)

Capture and play voice with Asterisk ARI -

there channel ari demo in wich can control channel state: ring, answer, play silence, play tone or audio-file ( https://github.com/asterisk/ari-examples/tree/master/channel-state , https://wiki.asterisk.org/wiki/display/ast/ari+and+channels%3a+manipulating+channel+state ) possible receive chunks (parts, buffers, etc.) of call voice (which created remote subscriber) or write chunks of voice, example array of bytes (not file) in audio format (alaw, ulow etc). you can use asterisk eagi interface voice data. other option use record or mixmonitor app record channel(channel have put stasis allow dialplan control ari) "write chunks of voice" can done application playback also can create own application using c/c++, compile asterisk , result want. no, can't redirect voice directly using ari.

i using checkstyle reportings source-code. question magicnumbercheck . i using date/(org.joda.)datetime in source code this: datetime datetime = new datetime(2013, 2, 27, 23, 0): datetime.plushours(57); is there way suppress magicnumbercheck notifications if magic number within date or datetime? you can use suppressioncommentfilter check this. configure properties values (in checkstyle configuration file) <module name="suppressioncommentfilter"> <property name="offcommentformat" value="check\:off\: ([\w\|]+)"/> <property name="oncommentformat" value="check\:on\: ([\w\|]+)"/> <property name="checkformat" value="$1"/> </module> now required lines, can like //check:off: magicnumber datetime datetime = new datetime(2013, 2, 27, 23, 0): datetime.plushours(57); //check:on: magicnumber this suppress magicnumber checks , rest checks work here. you can su...
