Sure SAS and SAS/GRAPH is good to plot (control) charts. See example here, But if you are a R lover you can also submit R script in SAS to do any analysis or charting you want. How?
SAS 9.3 can be used to run R scripts and packages within SAS/IML proc. To do that the following needs to be done:
1. Check if your SAS instance support R language. Just submit "proc options option=RLANG; run;" and check the sas log. If that is not supported, do next:
2. Add the following line at the end of the config file:
C:\Program Files (x86)\SASHome\SASFoundation\9.3\nls\en\sasv9.cfg
-RLANG
3. Install R-2.15.3 for Windows (32/64 bit) (note the R version 3 is not supported by SAS at this point)
4. Insert R-script to the following SAS/IML script:
proc iml;
submit / R;
..... your R scrpt is here ....
endsubmit;
5. Some simple test R-scripts samples to run in SAS is below:
proc iml;
/* Comparison of matrix operations in IML and R */
print "---------- SAS/IML Results -----------------";
x = 1:3; /* vector of sequence 1,2,3 */
m = {1 2 3, 4 5 6, 7 8 9}; /* 3 x 3 matrix */
q = m * t(x); /* matrix multiplication */
print q;
print "------------- R Results --------------------";
submit / R;
rx <- 1:3="" 1="" matrix="" nrow="1) " of="" sequence="" span="" vector="">
rm <- 1:9="" 3="" byrow="TRUE)" matrix="" nrow="3," span="" x="">
rq <- matrix="" multiplication="" nbsp="" rm="" rx="" span="" t="">
print(rq)
endsubmit;
More complex example: Call R Packages from PROC IML
And finally my own script to build IT-Control Chart against CSV data is following:
proc iml;
submit / R;

cchrt <- appsdata.csv="" header="T," ocuments="" read.table="" sep="," sers="" span="" workshop="">
plot (cchrt[,1],cchrt[,2],type="l",col="black",ylim=c(0,0.15),lwd=1.6,ann=F)
points (cchrt[,1],cchrt[,3],type="l",col="red", ylim=c(0,0.15),lwd=1,ann=F)
points (cchrt[,1],cchrt[,4],type="l",col="green",ylim=c(0,0.15),lwd=1,ann=F)
points (cchrt[,1],cchrt[,5],type="l",col="blue", ylim=c(0,0.15),lwd=1,ann=F)
points (cchrt[,1],cchrt[,6],type="l",col="MAGENTA", ylim=c(0,0.1),lwd=1,ann=F)
mtext("I/O Time/Thrd", side=2, line=3.0)
mtext("hours of week", side=1, line=3.0)
mtext("IT-CHART", side=3, line=1.0)
legend(10,0.16,c("Actual","UpperLimit","Mean","LowerLimit"),
col=c("black","red","green","blue"),lwd=c(.2,.1,.1,.1),bty="n")
endsubmit;
The code is similar to the one I published in my other post here. And below is the result:

Der Umgang mit Cloud-Diensten hat sich durch die Einführung von ISO 27017 deutlich verändert. Diese Norm legt konkrete Sicherheitskontrollen fest, um Daten in der Cloud zu schützen. Bei einer Weiterbildung im Bereich cybersecurity ist es wichtig, diese Standards zu kennen, um Schutzmaßnahmen effektiv umzusetzen. Mehr Infos dazu finden Sie auf csvisor.de, wo praktische Tipps für die Implementierung gegeben werden. In der Praxis bedeutet das, dass Unternehmen ihre Zugriffsrechte regelmäßig prüfen und Multi-Faktor-Authentifizierung aktivieren sollten. Die Einhaltung dieser Regeln kann verhindern, dass Angreifer sensible Daten bei einem Angriff wie dem SolarWinds-Hack ausnutzen. Für Fachleute in der cybersecurity weiterbildung ist es entscheidend, diese Standards regelmäßig zu aktualisieren und auf dem Laufenden zu bleiben.
